The ultimate guide to recursion interviews in JavaScript. Developed by FAANG engineers. Practice with real-world interview questions and get interview-ready in just a few hours.

If you’ve ever struggled with solving problems using recursion, or if you have to brush up your skills for an interview, this course is for you.

We'll start with the basics of what recursion is and why it’s important before diving into practicing solving actual questions. You’ll have access to detailed explanations and visualizations for each problem to help you along the way. 

By the time you have completed this course, you’ll be able to use all the concepts to solve complex real-world problems. We hope that through practicing recursion, you will be able to ace all recursion related questions in interviews at top tech companies.

Recursion for Coding Interviews in JavaScript

# Iterative Vs. Recursive
 
Both recursion and iteration are used for executing instructions repeatedly until some condition is satisfied.

So where does the difference lie between Iteration and Recursion? Let’s discuss a few factors that differentiate them from each other in this lesson.

Recursion refers to a situation where a function calls itself again and again until some *base condition* is reached.

Iteration refers to a situation where some statements are executed again and again using loops until some condition is satisfied.

In this lesson, we'll highlight the key differences between Iterative and Recursive functions.
