How can I write this map function in the pre ES6 format?

Hi I have this map function I found in a tutorial, and I’m interested as to how I’d write this in the old way – i.e writing the word "function" rather than the "=>" arrow format.

const example = spaceships.map((spaceship) => ({
    homePlanet: spaceship.homePlanet,
    color: spaceship.color
}));

I assumed that I could write it like this, but I get an error when adding the extra brackets.

const example = spaceships.map(function(spaceship) ({
    homePlanet: spaceship.homePlanet,
    color: spaceship.color
}));

>Solution :

You have to add a return

const example = spaceships.map(function (spaceship) {
  return {
    homePlanet: spaceship.homePlanet,
    color: spaceship.color
  }
});
