Ecmascript

This led to the eventual agreement in early 2009 to rename ECMAScript 3.1 to ECMAScript 5 and drive the language forward using an agenda that is known as Harmony.

TypeScript 5.5 brings inferred type predicates, regular expression syntax checking, performance optimizations, and support for ECMAScript Set methods.

A TS-script compiles into plain JavaScript and can be executed in any JS host supporting ECMAScript 3 or higher.

By default, only the JScript and VBScript modules are provided; third party implementations like ScreamingMonkey (for ECMAScript 4 support) can also be used.

Content can be animated by manipulating the DOM using ECMAScript and the scripting language's built-in timers.

ECMAScript 2015 was released in June 2015.

First, Brendan Eich and Mozilla rejoined Ecma International as a not-for-profit member and work started on ECMAScript for XML (E4X), the ECMA-357 standard, which came from ex-Microsoft employees at BEA Systems (originally acquired as Crossgain).

It is an enhanced superset of the ECMAScript programming language, with a classical Java-style class model, rather than JavaScript's prototype model.

So by 2003, the original ECMAScript 4 work was mothballed.

The current version is ECMAScript 2016, released in June 2016. citation Later developments JavaScript has become one of the most popular programming languages on the Web.

The default scripting language is ECMAScript (closely related to JavaScript ) and there are defined Document Object Model (DOM) objects for every SVG element and attribute.

The development of ECMAScript 4 was never completed, but that work influenced subsequent versions. citation While all of this was happening, the open source and developer communities set to work to revolutionize what could be done with JavaScript.

The resultant ECMAScript specification allowed JavaScript support by multiple web browsers and its use as a cross-browser scripting language, long after Netscape Navigator itself has dropped in popularity.

This led to the official release of the language specification ECMAScript published in the first edition of the ECMA-262 standard in June 1997, with JavaScript being the most well known of the implementations.
