Recursion in JavaScript

“ Let us understand recursion ”

Image of JavaScript

Recursion is a process in which we define a step or a process and let the code do the rest steps by this we achieve the same result with less coding

Recursion is a process of calling itself

To put an end to the process we must define the base case

So what is the base case? let's understand that with an example

Now to the point what if we don't mention the base case or provide a proper base case, In such we get a stack overflow error

This is because the function will go on calling itself all these function calls will be put on to the stack when the stack is full and we dint get a base case the result will not be returned so we get a stack overflow error

Find the factorial of a number using recursion
