What's the difference between insert(), insertOne(), and insertMany() method?

Question

What\'s the difference between insert(), insertOne(), and insertMany() methods on MongoDB. In what situation should I use each one?

Answer 1

There is also a difference in error handling, check here. The insert command returns a document in both success and error cases. But the insertOne and insertMany commands throws exceptions. Exceptions are easier to handle in code, than evaluating the returned document to figure out errors. Probably the reason why they are deprecated in the drivers as mentioned in sstyvane's answer.
