Factorialize a Number
Return the factorial of the provided integer.
If the integer is represented with the letter n, a factorial is the product of all positive integers less than or equal to n.
Factorials are often represented with the shorthand notation n!
For example: 5! = 1 * 2 * 3 * 4 * 5 = 120
Only integers greater than or equal to zero will be supplied to the function.
SOLUTION:
function factorialize(num) {
if(num === 0) {
return 1;
}
return num * factorialize(num-1);
}
factorialize(5);
console.log(factorialize(5))
