function sayHiToGrandma (aWord) {
  var cantUnswer = "I can't hear you!";

    return yesUnswer;
  }
  else if ("I love you, Grandma." === aWord) {
    return lovUnswer
  }
}

trick: With this condition aWord.toLowerCase(aWord) === aWord it is checked if the string is lowercased. To the left side, the function to lower case the string is called and then it is checked if it is the same with the string before the transformation. 💡

thought: The Revision 4 is the conditional expressed with the switch with various case situations. It is out of the lesson added version of the code, without the mocha tests to pass.
case aWord.toLowerCase(aWord) === aWord : unswer = "I can't hear you!";
this kind of case is not throwing an error but it is not working. 🐛

ty =)
Note: Although there are 3 tests for sayHiToGrandma(), you only need to write one function. This function should be able to handle all three test conditions:
what is this function?

Thank you for this
It looks like this is your version of how you came up with?
It does work and I just altered it a little so i can understand more, and again it works thank you!

THANK YOU THANK YOU!!!

THANK YOU.
