I'm building an app to check the expiration dates of items. The functionality of the app works but I want to be able to check if a string includes a sub-string in order to run my function which is a countdown timer. I haven't included much of the code but it should be sufficient. Code is Bellow 

var userInput = prompt("What item would you like to look up?");
  switch (userInput) {
    case userInput.includes("cous cous"):
//run a setInterval function

Yes you can. But you probably shouldn't. ;-) – T.J. Crowder Mar 17 '20 at 15:18

case expression: resolves the expression and does an equality test of that value against the userInput.

Use an if() statement for this type of thing.
