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.
