JavaScript (a dialect of ECMAScript) is a high-level, dynamic, multi-paradigm, object-oriented, prototype-based, weakly-typed, and interpreted language traditionally used for client-side scripting in web browsers. JavaScript can also be run outside the browser using a framework like Node.js, Nashorn, Wakanda, or Google Apps Script. Despite the name, it is unrelated to the Java programming language and shares only superficial similarities.
