First improve your code to fix the error:

 let db = await MongoClient.connect(MONGO_URI, { useNewUrlParser: true }); db = await db.db(); const collection = db.collection('sample_restaurants');

You have two different ways to get the data.

1- If your results are not a lot, you can get all of them in once and then print them.

 const results = await collection.find({}).toArray(); console.log(results)

2- If the number of the records is something like 2 million records, you can not use it this way. Have to create a cursor and then get them one by one.

 const cursor = collection.find(); while(await cursor.hasNext()) { const record = await cursor.next(); console.log(record); }
