const trekkies = [
  { id: 0, name: "Piccard", planet: "Earth" },
  { id: 1, name: "Spock", planet: "Vulcan" },
  { id: 2, name: "Kirk", planet: "Earth" },
  { id: 3, name: "Worf", planet: "Gault" }
];

const findTrekkiesByPlanet = planet => {
  return trekkies.filter(trekkie => trekkie.planet === planet);
};

console.log(findTrekkiesByPlanet("Earth"));
// [0: Object {id: 0 name: "Piccard" planet: "Earth"}
// 1: Object {id: 2 name: "Kirk" planet: "Earth"}]
