Asynchronous Processing and Optimization

No matter what experience you have in programming with JavaScript, you likely do not fully understand the language. This concise yet deeply thoughtful guide is dedicated to new asynchronous capabilities and performance enhancement tools that enable the creation of complex... single-page web applications while avoiding the "callback hell".
As in other books in the "You Don't Know JS" series, you will become familiar with the non-trivial features of the language that programmers fear so much. Only by equipping yourself with knowledge can you achieve true mastery.

The book covers the following topics:
- Old and new methods of asynchronous programming
- Using JavaScript promises to solve the "inversion of control" problem
- Applying generators for asynchronous execution in a sequential manner
- Improving performance using web workers, SIMD, and asm.js
- Methods for timing and optimizing expressions and commands
