Is this small Javascript function written in an old fashioned way?

function trueAns(q) { answers[q] = 1; }

Since EC16, is there a shorter way to right it? I recall I've seen in some course here that there is a way to write vars in a more efficient way since ES15 or 16. That's why I'm asking.

I think you might be talking about this course " Introducing Arrow Function Syntax".

The "shorter" way is this:

// Original:
function max(a, b) {
  if (a > b) {
    return a;
  } else {
    return b;
  }
}

// "Shorter":
var max = (a, b) => {
    if (a > b) {
      return a;
    } else {
      return b;
    }
}

// Longer:

var max = function (a, b) {
  if (a > b) {
    return a;
  } else {
    return b;
  }
}
