      reproduction code:

      const MongoClient = require('mongodb').MongoClient;
MongoClient.connect('mongodb://localhost', (err, db) => {
  let test = db.collection('test');
  return test.insert([{a: 1}, {a: 1}, {a: 1}, {a: 1}, {a: 1}, {a: 1}])
    .then(result => console.log(result.insertedIds.length))
    .then(() => db.close());
});

      This is the same as a call to `test.insertMany(<data>,

      { ordered: false }

      `, which also returns 7 inserted ids due to the fact that the internal representation of the ids is 1-indexed (rather than starting at 0).
