Find Factorial of Number Using Recursion in JavaScript

This tutorial explains how to find the factorial of a number using recursion in JavaScript.

The factorial of a positive number n is given by:

factorial(n) = 1*2*3*...*n
or,
factorial(n) = n * factorial(n-1)     //using recursion method

Example 1: Find Factorial of a Number n using Recursion

// program to find the factorial of a number
function Factorial(n) {
    if (n == 0) {
        return 1;
    }
    else {
        return n * Factorial(n - 1);
    }
}

console.log(Factorial(5))
console.log(Factorial(4))

Output
