History and Evolution of Programming Languages

Timeline of general-purpose programming languages by Denis Sureau

Selection criteria: A programming language enters the history if it has a compiler or an interpreter or if it has inspired other programming languages. New languages with innovative features are listed if we can produce programs in this language.

Evolution of programming languages

- Years 50: Creation of high-level languages ​​(closer to humans).
- Years 60: Expansion of specialized languages​​. Forth. Simula I. Lisp, Cobol. Trying unsuccessfully to impose general languages​​: Algol, PL / 1.
- Years 70: Duel between structured programming with Pascal and efficiency of C language. Basic generalized on personal computers from 1977, until the late 80s.
- Years 80: Experimentating other ways including objects. ML. Smalltalk. On computers, we now use C, Pascal, Basic compiled.
- Years 90: Generalization of object-oriented programming with the performance of microcomputers. Java, Perl, Python languages ​​in addition to microphones.
- 2000s: Internet Programming (and future innovations, see end of text).
- Years 2010: Concurrency and asynchronicity. JavaScript and Go languages among others help to create online fluid applications.

First language

Ada Lovelace and Babbage and its nephew were writing programs for the project of "difference engine", and then the "analytical engine".
In 1945, the german K. Zuse, inventor of the Z3 computer would have defined an evolved language for this engine (with arrays and records). Few documents of the epoch about this language exist.

Assembly

Assemblers exist since the beginning of computers. They associate a symbolic name to the machine-language code, for example:

add bx, 4
cmp [adr], 3
jmp address 
Assembly programming is no longer frequently practiced, even to build fast routines...

Autocode - 1952

Alick E. Glennie

Implemented firstly on Mark 1, then on other computers, this is a symbolic code.

IPL - 1956 - Information Processing Language

A. Newell, H. Simon, J.C. Shaw

Low-level list processing language. Implements the RECURSIVITY.

Fortran - 1954-1958 - FORmula TRANslator system

John Backus and other researchers at IBM

Language dedicated to mathematical calculations.
Fortran II (1958) introduced SUB-ROUTINES, FUNCTIONS, LOOPS, a primitive FOR control structure.
Identifiers were limited to six characters.

Lisp - 1958-1960 - LISt Processing

Mac Carthy

Functional language for list processing.
It is purely recursive, and not iterative. There is no difference between code and data.

IAL - 1958 - International Algebraic Logic

First name for Algol 58, never implemented.

Algol - 1960 / Algol W - 1966 / Algol 68 - ALGOrithmic Language

Defined by an international consortium of computer science specialists, coordinated by IFIP.

Algol Génie

This was the fist universal language to be machine independent.
Introduces the use of the BNF (Backus Naur Form) grammar to create a syntax parser.
Introduces BLOCKS of STATEMENTS, and LOCAL VARIABLES inside a block.
Recursivity was implemented but with reticence as this was considered as useless!
Uses DYNAMIC ARRAYS, and this means that following language (Pascal, C) have regressed by using static arrays, for better performance.
It has IF THEN ELSE, FOR, the := symbol for assignment (used then by Pascal), a SWITCH with gotos, the BEGIN END markers, the WHILE loop.

Algol W by Niklaus Wirth in 1966 was using RECORDS, that are dynamic data structures, CASE, passing parameters by value, precedence of operators.
The same year, Niklaus Wirth has created Euler, a language between Algol and Pascal.

Algol 60 was still oriented toward mathematical calculations. To try to reach the original goal of a general purpose language, a new version has been started in 1964, Algol X, renamed further Algol 68.
Algol 68 was using the =+ sign to merge both assignment and add.  It has introduced UNION and CAST of types.  It owns IF THEN ELIF FI, CASE, GOTO, user-defined operators.
Incremental compiling was not allowed.

Cobol - 1960 - COmmon Business Oriented Language

Defined by a committee, the CODASYL, COnference on DAta SYsystems Languages

The committee under the auspices of the Department Of Defense, and manufacturers, universities and users, worked from may 1959 to april 1960.
Grace Murray Hopper, who had designed Flow-Matic, a compiled language in the 50's, has participated to the committee.
Cobol is a classical procedural language aimed at enterprise management, in wich a program is divided in 4 divisions: identification, environment, data, procedure, and they may be divided in sections. It was founded on data and a program must describe precisely the hardware and input/ouput data format.
It introduced the RECORD data structure. Programs are documented by the syntax and are all but ligthweight...

APL - 1964 - A Programming Language

K. Iverson

Language using a mathematical notation, with lot of operators. A unique type, the array.
Defined from 1957 to 1960, implemented in 1964.

Basic - 1964 - Beginner’s All-purpose Symbolic Instruction Code

John Kemeny, Thomas Kurtz

Description

Has been designed in 1963, to be easy to learn and has been implemented in 1964. The first version was compiled, then it becomes interactive and interpreted. Each line has a number to allow GOTOs statements to jump to the line!
Bill Gate and Paul Allen have win an international contest by designing and implementing a fast and compact Basic, firstly for the Altair (in 4 kb memory!) and then on other micro-computers.
Micro-computers were delivered with Basic in ROM until late 80.
In 1977, the Apple II was sold with an integer Basic. Then the Applesoft Basic of Microsoft with floating-point. Applesoft was using two-letter identifiers! Sub-programs were called by GOSUB to line numbers.
The first PC from IBM, (in 1981) was using MS-DOS from Microsoft and its interpreted Basic (Basica). In 82 Microsoft produced its first compiled Basic (Quick Basic).
Pascal and C have replaced Basic in the same decade. Microsoft still uses Basic. Visual Basic for application, ASP for the web, and applications are extended with a language (macro) that is basic also.
True Basic, by the original authors of the language is compiled and no longer uses line numbers.

Iswim - 1965 - If You See What I Mean

P. Landin

First purely fonctional language, in the mathematical sense. The first to use LAZY EVALUATION.

Attribute grammars - 1965

Donald Knuth

Completing the BNF method, attribute grammars describes the semantic of languages to be made of functions. This type of grammar helps the building of compilers.

Simula 67 - 1962-67

Ole-Johan Dahl, Kristan Nygaard

The Simula project started in 1962. The goal was to build a tool to describe discrete event system, or network, and a language to program simulating real world.
Was firstly designed as an Algol extension.
In 1964, Simula 1 has been implemented on Univac 1107. It was used to control administrations, airports, planning, transport, or social systems.
This was a specialized tool.  In 1966, it has been decided to make it an universal language. Several projects has been launched with the help of several makers (IBM, Univac, Digital) and this leaded to Simula 67.
This universal language has introduced CLASSES, INHERITANCE and OBJECTS that are instances of classes. Classes allow to link functions (methods) to objects.

Logo - 1966

Fuerzeig, Seymour Papert, and others

Aimed to teach programming to children, near Lisp, and based on moving a "turtle" on the screen.

Snobol 4 - 1967 - StroNg Oriented symBOlic Language

D. J. Farber, R. E. Griswold, F. P. Polensky at Bells Labs

Snobol appeared in 1962.
Snobol 4 is the first stable distributed version of Snobol, available in 1967.
This is a processor of strings, founded on the principle of pattern-matching, concatenation and alternation.
It was the first language to implement associative arrays, indexed by any type of keys.
It allows to run code stored inside strings.
Data types are: string, integer, real, array, table, pattern and user-defined types.

CPL - Combined Programming Language

Cambridge and London Universities

This was a combination of Algol 60 and functional language aimed at proof of theorems. It was using polymorphic testing structures. Typed language with the "any" joker type. Had list and array.
Complex, was not implemented. I quote it only because it was a step toward the design of the C language.

BCPL - 1965? - Basic CPL

Martin Richards

It has been intended to be a simplified version of CPL.
Was using these control structures: FOR, LOOP, IF THEN, WHILE, UNTIL, REPEAT, REPEAT WHILE, SWITCH CASE, etc...
Owns procedures and functions, unlike C.
Block delimiters were $( ..... $) which has inspired probably /* ... */ in C.

PL/1 - 1965? - Programming Language number One - Originally NPL (New Programming Language)

IBM

Ibm for links on compilers.

The language was designed to be general-purpose and modular.
Keywords are reserved only in the context where they are used as keywords.
It is more hardware independent than predecessors. These types are recognized: fixed, real, complex, character, bit, bin, pointer, picture, file, etc.... Data have default attributes (as precision for example), that depends upon the context.
These compound types are built-in: array, structures, unions, and combinations of them. IF THEN and SELECT .. WHEN .. OTHERWISE are conditional structures, and variations on the DO structure allows various conditional loops.
Storage classes are introduced: automatic, static (life of the program), controlled, based. Exceptions are implemented.

Pascal - 1970 - Named from the french mathematician Blaise Pascal

Niklaus Wirth

Description

Language aimed to ease the building of compilers, and to lead teaching by forcing to a structured programming.
UCSD Pascal, written by a group of programmers leaded away by Kenneth Bowles is the first version for micro-computers. It compiles programs in P-code, that is portable and interpreted (as Java later). It included a complete development environment, a principle used successfully further by Turbo Pascal.
In 1981, a role playing game written in Pascal, Wizardry, has had a big success on Apple II.
When Turbo Pascal (by Anders hejlsberg) appeared in 1983 , fast and having a complete IDE, the language gained success and is still widely used.
Control structures are near C ones.

Forth - 1971 - Fourth reduced to Forth by the constraint of 5 letters of the IBM 1130

Charles H. Moore

Defined during 60+, seems to have been implemented in 1971. 
Language for astronomical instruments using a stack to replace variables.
Its goal was to be the fourth generation language.

Smalltalk - 1972

Alan Kay and the Software Concept Group

This is a fully object oriented language wich runs always inside a graphical environnment, with windows, mouse, etc...

C - 1973 - C is the successor of B, which is the successor of BCPL

Dennis Ritchie

Description

It was firstly destinated to program the UNIX operating system, but has become quickly universal thanks to its portability and speed.
Allows incremental compiling.  In 1965, ATT programmers were using Bcpl to work on implementing Unix. Displeased with this language, they made it evolve to a new version named B, then to a new language named C.
This was the evolving of the hardware that instigate to create C. Bcpl and B was using integer for pointers, but this was not working on the new computers.
Bcpl has no type (as Php or other modern scripting languages!). The declarations int i, char b were created in C. Other types will appear later.

The += operator comes from Algol 68 (but was written =+)
In Bcpl, a block of statements was enclosed inside the (* and *) symbols as the comment in /* and */ and sub-expressions inside ( and ). I suppose this symbolism was intended to denote that anything is an expression in the language, and also to reduce the parsing time. The C language simplified the writting with the { and } symbols, that does the original idea doesn't remains.
Union and cast come from Algol 68.
++ was already in the B language.
The keyword "include" comes from PL/I.
The preprocessor was implemented in 1973, and C has been used from this date to write Unix, but Ritchie worked on it since 1969. The language has evolved until 1980. .

Prolog - 1970+

A. Colmerauer, D. Roussel

GNU Prolog

Has been developped both in France at Aix-en-Provence and at Edimburg. 
Has introduced LOGIC PROGRAMMING. A program is made of Horn clauses.
Prolog is declarative, its system of logic inference is an engine of resolution.

SQL - 1970+ - Standard Query Language

IBM

Description

Language of query for relational databases. Successor of the Square language.

Awk - 1974 - First letters of authors' names

Aho, Kerninghan, Weinberger

Word processing language based on regular expressions, using a pattern-action principle.

Scheme - 1975 - From "schemmer"

Gerald Jay Sussman and Guy L. Steele at MIT

Chez Scheme Stklos

Language derived from Lisp but simplified. The types are boolean, integer of indefinite size, rational and complex, characters, symbols, vectors, oriented pairs, lists, associative lists, hash tables. The S-expression generic type is used to extend the language.
It is often used as a scripting language, by the Gimp for example. Standard.
The language and development tool Hop from Inria is Scheme extended into a functional HTML dialect to build Web 2.0 application.

Plasma - 1975

Carl Hewitt  

Language of actors. Implemented in Lisp.

Sasl - 1976 - Saint Andrews Static Language

D. Turner

Aimed to teach the functional programming. 
Comes from Iswim, unlimited data structures.

Icon - 1977

Griswold

Procedural language, with word processing function as Snobol4, and powerful constructs.
It has structured types: list, set, table (dictionary).
A list is declared: name := [ "word", "word", number, etc...]
A list may be indexed in the form a[i] or be used as a stack.
A "set" hold elements without doubloons, and has several functions: union, intersection, removing.
The RANGE construct is written:    a to b     where "to" is a keyword and "a" and "b" are variables..
A range may used inside an expression or as argument of a function. The expression or the function are called with each value in the range.
  Ex: write(1 to 5) will display 1, 2, 3, 4 ,5.
Expression don't return a boolean value, but are either evaluated or rejected. The operation are executed if the expression may be evaluated. This is the first language where expression evaluating it leaded by the GOAL.
There is a statement of the C language: if ( x= expression) ... which means: assign to x the result of the expression, and if a is non zero, then..., this construct is generalized in Icon, if the expression may be evaluated, x gets the value, else x remains unchanged and the condition is ignored.
The EVERY..DO construct associated to an expression works as an iterator. As the range.
The ALTERNATION is another powerful construct. It allows to use a sequence of parameters until a result is obtained. The symbol is "|".
For example the statement : if a | b | c = 0 | 1 means for....  if a or b or c is 0 or 1 then ...

ML - 1973? - Meta Language

R. Milner

Functional language inspired by Iswim.
Its goal was to proof theorem at the Edimburg University.
Functions are replaced by pattern models.
Implemented in Lisp.

Modula 2 - 1979 - MODUlar LAnguage

Niklaus Wirth

Modula 1 would be defined in 1977.  Implemented on the Lilith workstation at first.
The idea is to reduce the risk of error with coercive programming rules. However, it adds to Pascal some features of the C language. A call of function without argument is written f() as in C rather than f as in Pascal.
A program is splitted in modules with local scope, and interfaces for other modules. Use coroutines. Allows access to the hardware.
Was only used in Universities, because these new features has been added also to Pascal by the makers of compilers (the units of Turbo Pascal mainly).

Ada - 1980+ - Nickname of Ada Byron de Lovelace, first woman to program

Designed by a committee leaded by Jean Ichbiah, for the U.S. Department Of Defense.

Inspired by Pascal and Algol W. Is rather heavy.
Introduces GENERICITY of algorithms and a kind of primitive object orientation, but becomes really object oriented later.
Introduces PACKAGES, that are independent modules.

C++ - 1981-1986

Bjarne Stroustrup

Description

Object oriented version of C.
Introduces OPERATOR OVERLOADING. Methods may be inline.
Use // for one-line comment, that comes from BCPL, of which C is a successor!
Further, multiple inheritance and template (generic classes or functions) has been implemented.

Objective C, invented by Brad Cox in 1984, is another objet oriented version of C, inspired by smalltalk. No operator overloading. Used to write NextStep, the operating system of the Next computer, it has become the programming language of Apple with the return of Steve Jobs and therefore that of iPhone.

Standard ML - 1984

R. Milner, University of Edimburgh and Cambridge and Inria

Search for Standard ML Moscow on a search engine.

An implementation of ML.

Eiffel - 1985

Bertrand Meyer

Description

Procedural language fully object oriented , implementing persistency and programming per contract (using precondition and postcondition on functions). Was designed for security of software.
Compiled in C. May be interfaced with other languages. Has features of functional languages, generic classes, garbage collector.
An open source version exist, Sather, (from the name of a tower at Berkeley).

GAP - 1986 - Groups, Algorithms and Programming

Johannes Meier, Werner Nickel, Alice Niemeyer, Martin Schönert and others

The language has been defined to program mathematical algorithms.
It is interpreted, interactive an untyped. List and records are complex variables.
The syntax is that of Pascal with some differences. Comments for exemple are introduced by #.
An end of bloc is denoted by inverted keywords: if fi, do od.
The for loop has the forms: for in list, for in from to.
The language has procedures and functions.
What made it apart if that variables point out values and not memory addresses, and the form of a definition of function is as a call: x := function(arguments) body.
A function may be embedded inside another function.

Miranda - 1989 - From the name of a Shakespeare's heroin (Miranda, means for admirable in latin)

D.Turner

Inspired by Sasl and ML. Lazy evaluation: arguments of functions are evaluated only when they are used. Embedded pattern-matching, modules.

Caml - 1987 - Categorical Abstract Machine Language

Suarez, Weiss, Maury

Inria

Caml and Objective caml in 1996, has implemented ML.

Perl - 1987 - Practical Extracting and Report Language

Larry Wall

Destinated to replace the command line language of Unix, Sh, Sed and Awk, it kept the same ugly syntax. Used mainly for system administration, CGI scripts.
Includes lists and associatives arrays. The FOREACH control structure allows to scan lists.

Oberon - 1988

Niklaus Wirth

Successor of Modula 2 (and Pascal).
Several commonly used constructs are suppressed to reduce the risk or error! A garbage collector is added to.

Haskell - 1990 - Nickname of a logician, Haskell Curry

Purely functional language. Inspired by Miranda and Sasl.
Functional arrays, pattern matching.

ABC 1980-90 - ABC (equivalent to EZ in english)

CWI - Meertens, Pemberton and Guido Van Rossum

Scripting language elaborated at CWI in Netherlands, and the goal of which was to become a successor to Quick Basic or scripting languages of Unix.
Perhaps the first to use INDENTING to denote statements of a block: no markers as begin/end.
Another innovation, there is no file management, but rather persistency of the global variables: the value is stored from a session to another!
There are five types: number, string, list, composed (structure without fieldnames), array.

Python - 1991 - From the english TV movie "Monty Python Flying Circus"

Guido Van Rossum

Description

Scripting language with dynamic types. This is a replacement to Perl.
Inspired by ABC, but is extensible with C libraries, and object oriented.
As ABC, used evolved types: tuple, list, dictionary.
The slicing operator [a : b] allows to extract a sub-list from a list.
There is a version that compiles in Java bytecode, jython and ports for .NET.

Pov-Ray - 1991 - Persistence Of Vision (title of a mediocre science-fiction book).

D. & A. Collins, and contributors

Pov-Ray is a language for describing 3D images.

DisCo - 1992 - Distributed Co-operation

Reino Kurki-Suonio

Disco is a specification language for reactive systems with Pascal-like syntax. Constructs of the language are objects, event-driven functions (named here actions), and relations. A function is activated when a state of the system occurs and may be overwritten, this is named "refinement" in the language. Disco focuses on collective behavior. Layers are modules of the language. It is an system oriented language with objects and behavior (not action oriented as it is said in the presentation).

Ruby - 1994 - As the jewel, analogy with Perl

Yukihiro Matsumoto

Description

Ruby has been designed as successor to Perl and alternative to Python, to be clearer than the first one, and more object oriented than the second one. The syntax comes from these two languages, it want to be without surprise and natural but may be complex.
There is no new control structure as in Scriptol, but a lot of minor innovations to make the code smaller.
It is an interpreted language easy to extend. Statements are terminated by end of line. Blocks of statement and loop are delimited by "end". Most Python's features are present: associative arrays, iterators...
The originality is the dynamic object feature (adding methods to instances) and scope of variables denoted by a prefix.

Java - 1994 - Java (coffee)

James Gosling and other programmers at Sun

Description

Conceived at the beginning, in 1991, as an interactive language named Oak, was unsuccessful. But in 1994 has been rewritten for Internet and renamed Java. In 1995 navigators can run applets. In january 1996, Javasoft distributes JDK 1.0, the Java Developpement Kit.
Java is a object-orientedl language, near C++. It compiles in bytecode, interpreted on any computer. ..
It is simpler than C++: one class by file, automatic memory management, no pointers. No multiple inheritance nor operator overloading, but integrated multi-tasking.
Unlike C and C++, has only dynamic arrays.

PHP - 1995 - Personal Home Pages Hypertext Processor

Rasmus Lerdorf

Description

Multi-platforms scripting language, embedded inside HTML.
Near C but not typed. Variables are prefixed by the $ symbol as the shell of Unix or as Perl. The interpreter parses a html page that embeds php code and delivers a pure html page.
An extended library of functions allows webmasters to build dynamic pages.
Microsoft uses an equivalent language under Windows, ASP, near Basic.

JavaScript - 1995 (Has been firstly named LiveScript)

Brendan Eich at Netscape

Description

Scripting language to embedd procedural code into web pages.
May be used to other applications, XML based languages for example.
Share the syntax of C or Java, but with untyped variables. The element of the web page (window, table, etc...) are accessed through the Document Object Model.

UML - 1996 - Unified Modeling Language

Standard by OMG (Object Management Group) - Grady Booch, Jim Rumbaugh, and Ivar Jacobson

UML is the union of three modeling languages designed by the three authors above. The language uses a graphical notation to design software projects. A source is a diagram expressing objects and their interactions. A model is made of views and the combination of them describes a complete system. The model is abstract and domain-independent.

ECMAScript - 1997

Standard by the european standardization organisation E.C.M.A.

Standard to the language invented by Netscape, to let dynamic HTML pages client-side.

Rebol - 1997 (The design is older) - Relative Expression Based Object Language

Carl SassenRath

Interpreted, extensible scripting language that produces compact code. It is aimed at communication on Internet and distributed computing.
Has 45 types using same operators (Ex: date, money...). Use [ ] to enclose blocks of statements.

C# - 2000 - (C-sharp), want to succeed to C++

Anders Hejlsberg / Microsoft

Description

This is the main language of the .NET environment, to program software working thought Internet. As Java, it keeps the C syntax, a 34 years old language, with same improvments: garbage collector, no pointer, interfaces, multi-tasking...
C# compiles to intermediate language, the MSIL (MicroSoft Intermediate Language), and uses a multi-languages library, the CLR (Common Language Runtime). The originality of the .NET system is that various language may be compiled to MSIL and share their classes.
Other new features come with this language:
- structs are now special kind of object, passed by values.
- literals are objects also, with methods..
- attributes are descriptive objects attached to elements of the program and used by the runtime.
- properties: methods that may be used as variables (prop = 5 is equivalent to prop(5).
- foreach() to scan arrays (new only for Java and C++).
- delegate replaces pointer of functions of C.
There are improvements on Java also:
- event management is improved.
- operator overloading is present.
- simpler access to the the native system.

AspectJ - 2001 - Aspect for Java

Palo Alto Research Center.

Description

Aspect J is a Java extension that implements aspect oriented programming. A technique that modularizes crosscutting concerns. The unit is not the class, but a concern, that spans multiple classes. Concern may be, for example, properties, area of interest of a system and AOP describes their relationship, and compose them together into a program. Aspects encapsulates behavior that concerns multiple classes.

Scriptol - 2001 - Scriptwriter Oriented Language

Denis Sureau

Description

Scriptol is either compiled in PHP or in C++ or native, giving it a great portability. It is both a language for applications, for scripting and to make dynamic web pages.
Blocs of statements and control structures are not closed by "end" or "}" but, as in XML, with the form "/if", " /for", "/while" and so on...
The language has new control structures: "for in", "while let", "scan by", etc... The "composite if"structure eases to implement rules.
Variables and literals are objects. Basic object (number, text, etc...) and compound ones are created by direct assignment of a value or a list of arguments to the name.
Scriptol is destinated to evolve and to have, along classes, other high-level structures to allow programs to be nearest human thought.
Since October 2003, Scriptol allows to use XML as internal data structure.

Scala - February 2004

Description

Ecole Polytechnique Federale de Lausanne

Scala is a pure object oriented language that implements some Python features in Java syntax. It is statically typed and both procedural and functional. It currently runs on JVM and .NET.

Go - By Google, 2009

Description

Created by Google for its own development, but placed in the public domain under a free license, it is designed specifically for compilation speed.
It is a modern version of C++ without header files, with a simplified syntax. Classes are replaced by simple interfaces and inheritance is gone. It brings concurrency and includes a garbage collector, but with no substancial contribution to the design of programming languages.

Julia - 2010

Jeff Bezanson, Stefan Karpinski, Viral B. Shah, Alan Edelman. Sponsored by DARPA.

Description

The authors wanted to implement the best features of all other programming languages: objects, concurrency, homoiconicité, distributed computing, macro, generics. This with the most concise and clear syntax as possible. Julia is a significant step in programming languages.
Julia code is compiled through the LLVM JIT compiler and it runs like an interpreter.
Its main areas of application are scientific programs thanks to the expanded library, cloud with distributed processing and concurrency, and with the ability of a program to change itself, robotics.

Dart - By Google, 2011

Description

To replace JavaScript, Google feels has irrecoverable design flaws (this is not the opinion of all actors in the Web), it is similar to static languages ​​like Java, with classes, single inheritance, typed or dynamic variables. It does not bring real progress and is rather a regression with respect to JavaScript whose dynamic features have been a real evolution. JavaScript in version 5 will have static variables too, which reduces the value of Dart.

Rust - By Mozilla, 2006-2011

This system language originally created by Graydon Hoare in 2006 and taken in 2009 by Mozilla (its employer) has a compiler since 2011. Its syntax is derived from that of C with additions to manage concurrency and syntactic additions. It is object oriented and generic with polymorphic classes as in Haskell.
It is intended to be safer for the Web and taking better advantage of current processors.

Asm.js - By Mozilla, 2013

Description

This subset of JavaScript allows in combination with other tools to convert applications and libraries written in other languages ​​and use them in the browser. This makes of the browser a universal interface for software working online or offline on all operating systems and all types of devices, from desktop to smartphone.

From the present to the future

We see that after the plethora of dialects of the 70s, the invention of languages ​​stagnated about the syntax. Common languages​​, even recent ones like Java, C #, PHP, bring no change to the instructions, Go and Dart are even a regression. Only Julia is a real progress and exploit fully capabilities of current computers.
The use of JavaScript is spreading along with web applications offline.

Object-oriented languages
These languages allows to embed code inside HTML page and thus to combine statements and data. PHP, ASP, JavaScript are the most used ones. The .NET platform will allow any language to be embedded into HTML.
Classes are being replaced by dynamic objects and inheritance by combination.
Scripting languages
In the 2000s, several modern scripting languages offer a simpler and intuitive syntax: Python is the most widely used for now but is being replaced by Go. Ruby is mainly used for the Rail library but the trend is in Node and JavaScript.
Markup languages
XML was a major trend in the 2000-2010 but is then dedicated to graphical interfaces. For documents it trends to be replaced by JSON.
Microsoft uses XAML to define graphical interfaces, on the Web with the cross-browsers plug-in Silverlight or locally on .NET.
SVG is a format to embed graphics in webpages supported by all modern browsers. It may be used to design a user interface.
SQL
Thanks to Web applications SQL trends to be more and more popular, and so is now a part of modern programming.
Portability
Languages ​​become more portable thanks to LLVM and Emscriptem. The first for the virtual machine which runs on any system, the second by converting the LLVM code in JavaScript.
Conclusion
The development of mobile phones with their multiple operating systems foster HTML 5 as a development platform and related technologies: SVG, Canvas, CSS. JavaScript becomes the dominant language for client-side web applications.
Other trends are higher level for languages, programming by aspects, or by schemas with UML and further concepts, distributed computing on the cloud.
