Recursion, and recursive algorithms, have a reputation for being intimidating.But there's nothing magical about recursion. Its fearsome reputation is more a product of poor teaching than of the complexity of recursion itself.This book teaches the basics of recursion, exposes the ways it's often poorly taught, and clarifies the fundamental principles behind all recursive algorithms.It is project-based, containing complete, runnable programs in both Python and JavaScript, and covers several recursive algorithms for common tasks.
