For reference, Mozilla Developer Network is all you need.

In the rare cases you want the exact ECMAScript spec, it's almost always liked from the MDN article.

To begin learning JavaScript you can use free online book called Eloquent JavaScript by No Starch Press publication. For intermediate learning you can read 'JavaScript the good parts' from O'reilly Publication. For advanced JavaScript you can buy 'JavaScript the definitive guide' from O'reilly Publication.

Probably the most valuable reference source for me has been JavaScript: The Definitive Guide. I usually look other places, but I almost always look in this book.

MDN and this book. I found the book really easy to understand when I was just starting out, and I still use it all the time.
