No matter how much experience you have with JavaScript, 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 JavaScript programmers simply avoid. Armed with this knowledge, you can become a true JavaScript master.With this book you will: Explore old and new JavaScript methods for handling asynchronous programming Understand how callbacks let third parties control your program&;s execution Address the "inversion of control" issue with JavaScript 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
