Not work “mutation([“hello”, “hey”]) should return false” but everyone else is working.
function mutation(arr) {
var test = arr[0].toLowerCase();
var tar = arr[1].toLowerCase();
for(i = 0;i < tar.length;i++){
if (test.indexOf(tar[i]) < 0){
return false;
}else{
return true;
}
}
}
mutation([“hello”, “hey”]);
Instead indexOf the whole word, do it but for every letter of tar[1]. You can use method charAt(i) where for “i” you loop through every individual letter.
You’re only testing the first letter.
return exits your function. In your case you test the first letter and return either true or false based on that one test.

Good luck!

Format your code(wrap in back-ticks) so everyone can read it more easily. It is much easier to copy / paste formatted code for further testing too.
