Compare character in array

JavaScript
1

I’m having brain fart on how to comparing characters through each element in an array.

Can someone please give me some hints on how to proceed.

My code so far:

function mutation(arr) {

  let word1 = arr[0].toLowerCase();
  let word2 = arr[1].toLowerCase();

  for (let i = 0; i < arr.length; i++) {
    
    if (word1[i].includes(word2[i])){
      return true
    }
  }
  return false;
}

mutation(["hello", "hey"]);

Can you explain why you want to loop over the array of words?

Oh… shi** :slight_smile:

That is a very good question indeed! I should loop over word1 and then compare it to word2… :man_facepalming:
