Factorial Calculator

So basically, factorializing numbers makes it easier to figure out the number of combinations which is useful when calculating probabilities or statistics. … If the integer is represented with the letter n, a factorial is the product of all positive integers less than or equal to n. Example 5!, 10!, 25!

##For Example test 5! === return 12o
test 4! === return 24
test 1! === return 1
Should return true

function factorialize(num) { 
	let result = 1; 
	for(let i = num; i>0; i–){ 
		result *= i; 
		} 
		return result; 
	}

console.log(factorialize(5)) => 120 
console.log(factorialize(10)) => 3628800

1. We create variable result and initialize to 1;

2.Then we will create a loop where we create variable i = num, then i will always be greater than 0 and i will be deducted by one on each loop;

3.Then result will be result = result * i; or shorthand result * = result * i In the end we return result.
