You Don't Know JS: Scope and Closures

 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.
    How to use the DOM effectively to interact with browsers
    Discover how to use closures for synchronous and asynchronous tasks, including the creation of JavaScript libraries.
