Traceur Compiler

Traceur is a JavaScript.next-to-JavaScript-of-today compiler that allows you to use ES6 and experimental ES.next features by transpiling them to ES5. Version 0.0.111 is the latest stable release. It was developed by Google to inform the design of new JavaScript features and supports a wide range of proposals including async functions, generators, spread properties, and JSX. It provides both CommonJS and browser builds. Traceur is now largely superseded by Babel, but remains useful for legacy projects or understanding early transpiler design.
