Synopsis
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
