How do I get the objectID after I save an object in Mongoose?

Question

var n = new Chat();
n.name = \"chat room\";
n.save(function(){
    //console.log(THE OBJECT ID that I just saved);
});

I want to console.log the ob

With save all you just need to do is:

n.save((err, room) => {
  if (err) return `Error occurred while saving ${err}`;

  const { _id } = room;
  console.log(`New room id: ${_id}`);

  return room;
});

Just in case someone is wondering how to get the same result using create:

const array = [{ type: 'jelly bean' }, { type: 'snickers' }];

Candy.create(array, (err, candies) => {
  if (err) // ...

  const [jellybean, snickers] = candies;
  const jellybeadId = jellybean._id;
  const snickersId = snickers._id;
  // ...
});
