Master recursion in JavaScript to solve problems and excel in coding interviews with practical exercises and visualizations.

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

Nowadays, many programming languages such as *Haskell*, *Scala*, *JavaScript*, etc. use Functional Programming. An important concept of functional programming is *recursion*. Entire languages are now being based on recursion.

In general, problems that can be solved with a non-recursive code can also be solved by recursion. However, some problems can only be solved recursively.

> It is important to note that even if it is possible to solve any problem with recursion, it does not mean that we should.

Let's take a look at some pointers that will help us identify whether to use recursion or the conventional iterative method for solving a specific problem.
