What's the difference between "deletemany" and "remove" in mongodb?

What's the difference between the two commands here?
db.collection.deleteMany({condition})
db.collection.remove({condition})

They do the same. The difference is the values that return.

With remove():

> db.ticker.remove({"name": "Bitcoin"})
WriteResult({ "nRemoved" : 2 })

With deleteMany():

> db.ticker.deleteMany({"name": "Bitcoin"})
{ "acknowledged" : true, "deletedCount" : 2 }

As far as I can say,

> db.collection.deleteMany

Returns:	
   A document containing:
       > A boolean acknowledged as true if the operation ran with write concern or false if write concern was disabled
       > deletedCount containing the number of deleted documents

REF: db.collection.deleteMany

Where as

> db.collection.remove

return WriteResult

And to remove a single document, there a similar command, db.collection.removeOne where as with db.collection.remove you need to set and option called justOne option to limit delete to 1 document.

Otherwise I guess they are similar.

> node.js drivers

When talking about node.js drivers, remove has been deprecated (and may be removed in future releases) and deleteOne or deleteMany.

Hope this makes sense ....
