No matter how much experience you have with JavaScript, odds are you don’t fully understand the language. This concise yet in-depth guide takes you inside scope and closures, two core concepts you need to know to become a more efficient and effective JavaScript programmer. You’ll learn how and why they work, and how an understanding of closures can be a powerful part of your development skillset.

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

* Learn about scope, a set of rules to help JavaScript engines locate variables in your code
* Go deeper into nested scope, a series of containers for variables and functions
* Explore function- and block-based scope, “hoisting”, and the patterns and benefits of scope-based hiding
* Discover how to use closures for synchronous and asynchronous tasks, including the creation of JavaScript libraries

From the Author
The "You Don't Know JS" book series is intended to bring us all (myself included!) to terms with the reality that there's an awful lot of JS that we think we kinda know, but we don't really have total confidence in. Rather than leaving these topics to the misunderstanding, and treating certain things as a black box we can't understand, we dive deeply into them and try to uncover exactly how and why they work.

It is my hope that you will come away from these books with a much deeper confidence in, and appreciation for, JavaScript. Isn't it time we all start really knowing JS?
