JavaScript Language Reference Manual [closed]

Question

Is there a complete and a most updated and downloadable JavaScript Language Reference Manual!?

Answer 1

The closest thing to an official documentation is the ECMA specification. Implementors of JavaScript follow this specification.

However, the most widely used and penetrable (reading the spec for quick reference can be daunting) documentation is JavaScript at Mozilla Documentation Network. It has a lot of information that is handy for using JavaScript in the browser too.
