• ECMAScript (or ES) is a scripting-language specification standardized by Ecma International in ECMA-262 and ISO/IEC 16262. It was created to standardize JavaScript to help foster multiple independent implementations. JavaScript has remained the best-known implementation of ECMAScript since the standard was first published, with other well-known implementations including JScript and ActionScript. ECMAScript is commonly used for client-side scripting on the World Wide Web, and is increasingly being used for writing server applications and services using Node.js. ← Wikipedia
