JavaScript is NOT A PROJECT.
JavaScript is an implementation of the ECMAScript language standard and is primarily used in the form of client-side JavaScript, implemented as part of a web browser in order to provide enhanced user interfaces and dynamic websites. This enables programmatic access to computational objects within a host environment.
Because of its open standard yes it is open but not source :) .
Because a language standard can not be open-source but an implementation of it can be.
For example, the V8 engine, which is what Google Chrome uses is available, and so is theSpiderMonkey source code, which is used in Mozilla Firefox. There are more JavaScript engines, if you're interested.
