Questions tagged [javascript]

JavaScript (not to be confused with Java) is a dynamic, weakly-typed language used for client-side as well as server-side scripting. Use this tag for questions regarding ECMAScript and its various dialects/implementations (excluding ActionScript and Google-Apps-Script). Unless another tag for a framework/library is also included, a pure JavaScript answer is expected.
