Basic Algorithm Scripting - Mutations

Tell us what’s happening:

I can’t figure out why this problem needs to check for false then return true instead of the inverse if it returns a value greater than or equal to 0. I initially did it this way, where it checked

for (let i = 0; i < test.length; i++) {
    if (target.indexOf(test[i]) >= 0) {
      return true;
    }
  }
  return false;
}

A return statement immediately stops a function. So if you have return true inside of the loop, the very first time that a valid string is found, the function would return immediately and stop checking any other strings.
