The Recursive Book of Recursion

An accessible yet rigorous crash course on recursive programming using Python and JavaScript examples.

Recursion has an intimidating reputation: it s considered to be an advanced computer science topic frequently brought up in coding interviews. But there s nothing magical about recursion.
 
The Recursive Book of Recursion uses Python and JavaScript examples to teach the basics of recursion, exposing the ways that it s often poorly taught and clarifying the fundamental principles of all recursive algorithms. You ll learn when to use recursive functions (and, most importantly, when not to use them), how to implement the classic recursive algorithms often brought up in job interviews, and how recursive techniques can help solve countless problems involving tree traversal, combinatorics, and other tricky topics.
 
This project-based guide contains complete, runnable programs to help you learn:
 

 
Al Sweigart has built a career explaining programming concepts in a fun, approachable manner. If you ve shied away from learning recursion but want to add this technique to your programming toolkit, or if you re racing to prepare for your next job interview, this book is for you.
