Multiple Return Values, why?

In the last quiz, it said that if you ut mitlble return values in a function only the first one will run. BUT never the less it's possible to store more return values in a function. When you this by useful, and why do people want to store multiple return values in a function if only the first one will run?

A function could have a conditional that returns something based on its result. So, it has multiple return values, but only one of them will ever run 

function hi(x) {
  if (x === 5) {
    return 'ya'
  } else {
    return 'nah'
  }
}
