### **Cuéntanos qué está pasando:**

It’s wrong.?

_Tu código hasta el momento_\*

```javascript
function mutation(arr) {
 let arr1 = arr[0].toLowerCase();
 let arr2 = arr[1].toLowerCase();
 for (let i = 0; i < arr1.length; i++){
   if (arr2.indexOf(arr1[i]) < 0) return false;
     
   }
   return true;
 }
  

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

```
