This document provides an overview of JavaScript Development Tools (JSDT) 2.0. It discusses why JavaScript is important, outlines key updates and new features in JSDT 2.0, including support for ECMAScript 2015, Node.js runtimes and debugging, a JSON editor, integration with Bower/npm, and Grunt/Gulp. It also previews future plans for JSDT such as adding Closure compiler support and developing language services using the Language Server Protocol.
