With this concise and simple guide, you’ll learn how to usejQuery deferreds and promises, an elegant approach for managing asynchronouscalls in both client and server applications.

This book contains 18 examples that use deferreds to solve progressivelychallenging real-world programming problems, along with 75 stimulating puzzles(and their solutions) that will help you understand how and when to usedeferreds. You’ll learn new tricks in a fun way, and become immersed in thepractice of event-based programming.
