Mongodb – What benefit of using mongoose.Types.ObjectId instead of req.params.id to compare with the _id in Mongoose

For example

await Smartphones.findOne({_id: req.params.id})

await Smartphones.findOne({_id: ObjectId(req.params.id)})

To me it seem both return object, but I don’t if it have any benefit of using ObjectId when comparing

    If you are using ObjectId(req.params.id) it will try to parse the "req.params.id" value to mongoDB Object Id, if its unable to parse it throws an error as "req.params.id" is not a valid mongo object id

    If you are using MongoDB Compass to fetch some data, you can’t use the _id as a simple string, there you should use ObjectId for getting the data. An _id in the document can be of any form except an array, and the default format is ObjectId. The ObjectId is not just a simple format in MongoDB, other than that of a format it has some use-cases too, you can refer to this link
