Factorial function in JavaScript (with recursion)

#javascript #recursion #fctorial

Introduction

This is a simple program that computes the factorial of a number using recursion.

So, what is Recursion? 🤨

Recursion in programming is a technique or method of writing a function in which that function calls itself until a specified condition is met.
Recursion can be used to repeat an action without using a for or while loop.

A Simple Factorial Function in JavaScript.

Line 3 and 8 will stop the function from calling itself (i.e stops the recursion) when the value of n is less than or equal to 1.
If n is still greater than one then line 4 and 9 will will be executed and as you can see line 4 and 9 still calls its respective functions, that's recursion in action 😁.

Here is the result:

Note: 🙏 ✍

Make sure the condition to break your recursion is valid. If the condition is not valid you will run into an infinite recursion, this means your recursion will run forever and ever (hope you didin't say Amen 🤣). Have fun.
