With Early Release ebooks, you get books in their earliest form—the author's raw and unedited content as he or she writes—so you can take advantage of these technologies long before the official release of these titles. You'll also receive updates when significant changes are made, new chapters are available, and the final ebook bundle is released.

No matter how much experience you have with JavaScript, odds are you don’t fully understand the language. As part of the "You Don’t Know JS" series, this compact guide explores JavaScript types in greater depth than previous treatments, defining the problems of coercion, demonstrating why types work, and showing developers how to take advantage of those features.

The type system in JavaScript is subject to several misconceptions. Many developers believe that JavaScript has no types, but that's not the case. JavaScript uses a number of types behind the scenes, and has a sophisticated system of implicit and explicit coercion between the various types. This book gives you the complete story.

Like other books in this series, You Don’t Know JS: Types & Grammar dives into trickier parts of the language that many JavaScript programmers simply avoid. Armed with this knowledge, you can achieve true JavaScript mastery.

    Comments about oreilly You Don't Know JS: Types & Grammar:

    I don't think I've ever read a book this good on a programming topic. Everything was explained well, to the point, and extremely interesting. This, in my opinion, tops the first two parts of the series even though it's an early release, as I didn't feel like having to read some paragraphs twice (which I expect to often happen with in-depth discussions of unknown/unexpected technical issues). I was left with easily understanding many 'wtf' examples on JS that float around the internet outside of the examples given in the book, and getting a lot of ideas on how to make my code look nicer, and work better.
