JavaScript, developed by Netscape, is a simple language for beginners that is distinct from Java despite some syntactical similarities. The current standard for JavaScript is ECMA 262 5.1, with support varying across browsers, and it is not limited to web browsers, finding use in applications like Adobe Acrobat and Node.js. Historic anomalies have led to various names for the language, including JScript and ECMAScript.
