Recursion, in which functions call themselves, is a foundational structure for algorithms. If you find it hard to break a technical problem down into its simplest form, learning recursion may be just what you need. In this course, software engineer Mustapha Rufai provides a detailed guide to understanding recursion using javascript, exploring common use cases and detailing ways to approach these kinds of algorithmic challenges. Mustapha teaches you how to think recursively, and safely make javascript use this classic pattern. He then moves to showing you how to improve the performance of recursive algorithms, and presents a series of recursive technical interview questions along with his solutions.
