Factorize a Number

factorizeNumber.js

// 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


function factorialize(num) {
  var factoredNumber = num;
  if (num === 0 || num === 1)
    return 1;
  while (num > 1) {
    num--;
    factoredNumber *= num;
  }
  return factoredNumber;
}
console.log(factorialize(5));
