Tell us what’s happening:

all outputs are correct apart from the last two, i can’t get it where is my mistake

Your code so far

function mutation(arr){
  const firstEl = arr[0].toLowerCase();
  const secondEl = arr[1].toLowerCase();
  let val;

  for(let char of secondEl){
    console.log(char)
    if(!firstEl.includes(char)){
     val = false;
    } else{
     val = true;
    }
  }

  return val;
}

console.log(mutation(["Hello", "hello"])); // output: true

console.log(mutation(["Hello", "hey"])); // output: false

console.log(mutation(["Alien", "line"])); //output: true

mutation(["hello", "neo"])

When your code sees that “n” is not included in “hello”, it sets val to false, but does it stop there? Or does it evaluate “e” and set val to true?

Sorry for that, it was my first time here I accidently created duplicate topic. I tried to delete it but i couldn’t find option for that.

No worries. I thought you were trying to bump it…my mistake.

Happy coding!
