only()

The only method returns the items in the collection with the specified keys:

const collection = collect({
  id: 12,
  name: 'John Doe',
  email: 'john@doe.com',
  active: true,
});

const filtered = collection.only(['name', 'email']);

filtered.all();

// { name: 'John Doe', email: 'john@doe.com' }

collect([1, 2, 3, 4])
  .only([2, 12])
  .all();

// [2]

For the inverse of only, see the except method.
