This is a wiki for the ongoing specification work of Ecma TC39 , the technical committee tasked with standardization of the ECMAScript programming language. Most of the wiki is world-readable, meaning that anyone can view the pages.
In computer programming , a shim (from shim ) or shiv is a small library that transparently intercepts an API and changes the parameters passed, handles the operation itself, or redirects the operation elsewhere.
Webshims Lib is a modular capability-based polyfill -loading library, which focuses on accurate implementations of stable HTML5 features, so that developers can write modern, interoperable and robust code in all browsers. It is built on top of jQuery and Modernizr . Download Webshims Lib Main concepts
In web development , a polyfill (or polyfiller ) is downloadable code which provides facilities that are not built-in to a web browser. For example, many features of HTML5 are not supported by versions of Internet Explorer older than version 8 or 9, but can be used by web pages if those pages install a polyfill. [ 1 ] [ 2 ] Web shims [ 3 ] like HTML5 Shiv are a related concept. Polyfills can also be used to add entirely new functionality to browsers.

Prototype-based programming is a style of object-oriented programming in which classes are not present, and behavior reuse (known as inheritance in class-based languages) is performed via a process of cloning existing objects that serve as prototypes . This model can also be known as classless , prototype-oriented or instance-based programming. Delegation is the language feature that supports prototype-based programming.
Standard ECMA-262 ECMAScript® Language Specification Edition 5.1 (June 2011) This Standard defines the ECMAScript scripting language. The following file can be freely downloaded: This edition 5.1 of the ECMAScript Standard is fully aligned with third edition of the international standard ISO/IEC 16262:2011.
