Why my code is not working.
This is the challenge:
Return true
if the string in the first element of the array contains all of the letters of the string in the second element of the array.
For example, ["hello", "Hello"]
, should return true
because all of the letters in the second string are present in the first, ignoring case.
The arguments ["hello", "hey"]
should return false
because the string hello
does not contain a y
.
Lastly, ["Alien", "line"]
, should return true
because all of the letters in line
are present in Alien
.
Your code so far
function mutation(arr) {
let elem1 = arr[0].toLowerCase().split("");
let elem2 = arr[1].toLowerCase().split("");
for(let i = 0; i < arr.length; i++) {
if(elem1.indexOf(elem2[i]) < 0) {
return false
}
}
return true;
}
console.log(mutation(["hello", "hey"]));
