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

## Problem Statement
Here we've to find the number of *vowels* in a given string. We know that the *English alphabet* contains $5$ vowels:
$a, e, i, o, u$. Let's solve this problem by using both iterative and recursive methods.

### Iterative Method
To solve this problem, we have to traverse the entire string. Therefore, we can initiate a simple `for` loop.
