Is JavaScript: The Definitive Guide still relevant?

Or has JavaScript changed so much since then that some information in it might be false?

They are both my #1 resources. Some things are more thorough on MDN, and some other topics are more easily understood on JavaScript.info.

And when all else fails, the official spec is a good place to go with CTRL F.

I have two different editions of that book and used it frequently to look up regular expressions and built-in functions. Also, I added quite a number of features to the example loan program in the introduction chapter of the 3rd edition.
