Implement the Mutations Algorithm - for.. of loop passing all tests but one

JavaScript

Tell us what’s happening:

All tests are passing except the first

The array gets destructured into two variables, then each letter of the second word is checked against the first and if included returns true, otherwise returns false. Except for “hey” into “hello”..

Your code so far

function mutation (array) {

  let [ firstWord, secondWord ] = array;

  for (let letter of secondWord) {
    if (firstWord.toLowerCase().includes(letter.toLowerCase())) {
      return true;
    } else {
      return false;
    }
  }
}

how many iterations do you think your loop does? is it managing to check all letters in the word?
