What is causing my conditional operator to malfunction?

What is the reason for the output being undefined instead of "old" in this scenario?

function test(age) {
  return 12 < age ? "old" : "young";
}

test(15); 

Answer №1

Your current situation appears to be in good standing. It is imperative that you remember to return

function evaluateAge(age) {
  return age > 12 ? "old" : "young";
}

console.log(evaluateAge(15));

If you neglect to include a return statement, the function will automatically return undefined.
