You have a faulty keyboard. Whenever you type a vowel on it (a,e,i,o,u,y), it reverses the string that you have written, instead of typing the character. Typing other characters works as expected. Given a string, return what will be on the screen after typing with your faulty keyboard.

faultyKeeb.js

function faultyKeeb(str) {
  for (let i = 0; i < str.length; ++i) {
    if (['a', 'e', 'i', 'o', 'u'].includes(str[i])) {
      str = Array.from(str.slice(0, i)).reverse().join('') + str.slice(i+1, str.length);
    }
  }
  return str;
};
