Mutations : I use the procedureal code and need help

Tell us what’s happening:

I use the procedure of IndexOf to return the true or false values. However the code is failing on certain tests>
mutation(["hello", "hey"]) should return false.

Passedmutation(["hello", "Hello"]) should return true.

Failed mutation(["zyxwvutsrqponmlkjihgfedcba", "qrstu"]) should return true.

Passedmutation(["Mary", "Army"]) should return true.

Passed mutation(["Mary", "Aarmy"]) should return true.

Failed mutation(["Alien", "line"]) should return true.

Failed mutation(["floor", "for"]) should return true.

Passedmutation(["hello", "neo"]) should return false.

Passedmutation(["voodoo", "no"]) should return false.

Failed mutation(["ate", "date"] should return false.

Passedmutation(["Tiger", "Zebra"]) should return false.

failed mutation(["Noel", "Ole"]) should return true.

Your code so far

function mutation(arr) {
var value = arr[0].toLowerCase();
var test = arr[1].toLowerCase();
for (var i = 0; i <   value.length; i++) {
  console.log(test.indexOf(value[i]) < 0);
  if (test.indexOf(value[i]) < 0) return false;
 return true;

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

I reviewed my logic and rewrote the logic and it worked. Quoting Rosana Dana “Nevermind”

Good job figuring it out. Happy coding!

thanks. :slight_smile:
