factorialize.md

Task: Return the factorial of the provided integer.

Pseudocode:

• Get the integer value (n) as a parameter
  • If the the number is equal to 0
    • return 1
  • return the value of n multiplied by result of n - 1

Actual Code:

function factorialize(num) {
  // base case - if num is equal to 0, stop the recursion
  if (num === 0) {
    return 1;
  }
  
  // recursive case - will run except when num is equal to 0
  return num * factorialize(num - 1);
}

factorialize(3); // 6
