Need help: Selecting from Many Options with Switch Statements

Tell us what’s happening:
Describe your issue in detail here.
I’m trying to write a switch code but it doesn’t work for some reason. Can anyone explain to me why?

  **My code so far**
function caseInSwitch(val) {
let answer = "";
// Only change code below this line
switch (val) {
  case 1:
  answer === "alpha";
  break;
  case 2:
  answer === "beta";
  break;
  case 3:
  answer === "gamma";
  break;
  case 4:
  answer === "delta";
  break;

}


// Only change code above this line
return answer;
}

caseInSwitch(1);
