updating multiple values in update mongoose code example

Example 1: mongoose find multiple and update

Model.updateMany({}, {})

Example 2: Update multiple documents with different field value by id set. Mongoose

You can not update two documents at once with a MongoDB query. You will always have to do that in two queries. You can of course set a value of a field to the same value, or increment with the same number, but you can not do two distinct updates in MongoDB with the same query.
