Dialects
ECMAScript is supported in many applications, especially web browsers, where it is implemented by JavaScript, or, in the case of Internet Explorer, JScript. Dialects sometimes include extensions to the language, or to the standard library and related application programming interfaces (API) such as the World Wide Web Consortium (W3C) specified Document Object Model (DOM). This means that applications written in one dialect may be incompatible with another, unless they are written to use only a common subset of supported features and APIs.
