how to get the factorial of a number in javascript in a recursive way?

Question

I want to know how to find the factorial of number 4 in a recursive way. Although, I know the simple technique suppose.

let factorial = 1; for(let i=1; i<=4; i++){ factorial = factorial * i;} console.log(factorial)

Answer 1

If you want to learn and use same approach as the code.

You can do it this way

function factorial(n){
  return n === 1 ? n : factorial(n-1) * n;
}

So basically just do n * n-1 * n-2 * n-3... 1
For example 4, then the algorithm would run as follows: 5 * 4 * 3 * 2 * 1
When it reaches 1, the recursion should stop, because that's how factorial works
