  • 8. ECMA-262 (ISO/IEC 16262)JavaScript is an implementation of theECMAScript language standard and is typicallyused to enable programmatic access tocomputational objects within a host environment.It can be characterized as a prototype-basedobject-oriented scripting language that isdynamic, weakly typed and has first-classfunctions. It is also considered a functionalprogramming language [...] because it hasclosures and supports higher-order functions. Source http://en.wikipedia.org/wiki/JavaScript 8 | © 2012 IBM Corporation

  • 28. First Class Functions■ In computer science, a programming language is said to support first-class functions [...] if it treats functions as first- class objects. Specifically, this means that the language supports constructing new functions during the execution of a program, storing them in data structures, passing them as arguments to other functions, and returning them as the values of other functions. Source: http://en.wikipedia.org/wiki/First-class_function 28 | © 2012 IBM Corporation
  • 29. First Class Functionsfunction sayHello() { return “Hello World”}var x = sayHello; → x() → “Say Hello”var y = sayHello(); → y() → undefinedx → functiony → “Say Hello”var m = new Function("x", "y", "return x * y"); 29 | © 2012 IBM Corporation
  • 30. Higher Order Functionsfunction HelloWorld() { “sayHello” : function(whoAreYou) { return “Hello “+whoAreYou+”, nice to meet you” }, “getHello” : function() { return this.sayHello; }}var x = HelloWorld.getHello();x(“Peter”) → “Hello Peter, nice to meet you”; 30 | © 2012 IBM Corporation
