Tell us what’s happening:

I know where I’m going wrong, but I can’t figure out why this approach isn’t working.

Your code so far

function mutation(arr){
  let arrStart = arr[0].toLowerCase()
  let arrSecond = arr[1].toLowerCase() 
  for(let array of arrSecond){
    if(!arrStart.includes(array)){
      return false
    }
    else {
      return true
    }
  }
}

Hi there!

Your loop returns after checking only one character. Try to get into the habit of using console.log() to debug your code so you can see what it’s doing.

Happy coding!
