You Don't Know JS: Async & Performance

No matter how much experience you have with jаvascript, odds are you don't fully understand the language. As part of the "You Don't Know JS" series, this concise yet in-depth guide focuses on new asynchronous features and performance techniques—including Promises, generators, and Web Workers—that let you create sophisticated single-page web applications and escape callback hell in the process.

Like other books in this series, You Don't Know JS: Async & Performance dives into trickier parts of the language that many jаvascript programmers simply avoid. Armed with this knowledge, you can become a true jаvascript master.

With this book you will:
• Explore old and new jаvascript methods for handling asynchronous programming
• Understand how callbacks let third parties control your program's execution
• Address the "inversion of control" issue with jаvascript Promises
• Use generators to express async flow in a sequential, synchronous-looking fashion
• Tackle program-level performance with Web Workers, SIMD, and asm.js
• Learn valuable resources and techniques for benchmarking and tuning your expressions and statements
