I've been through two books in this series and very thrilled to dive deeper into next books.
Code samples are short, intention revealing and very informative. Topics covered: scope, different types of scope, modules, IFFE, hoisting, closures, polyfilling. The book is so concise, that it seems like every word is brushed until it shines, revealing the underlying truth about JavaScript and it's key differences from other languages. Kyle deserves every cent received at Kickstarter.

Learn about scope, a set of rules to help JavaScript engines locate variables in your code Armed with this knowledge, you can achieve true JavaScript mastery. 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. You'll learn how and why they work, and how an understanding of closures can be a powerful part of your development skillset.
