Learn What are the Different types of update methods in MongoDB - Part 11

You can use the update() method to update documents of a collection. The method accepts as its parameters:

a filter document to match the documents to update,
an update document to specify the modification to perform, and
an options parameter (optional).

To specify the filter, use the same structure and syntax as the query conditions.
By default, the update() method updates a single document. Use the multi option to update all documents that match the criteria.

To change a field value, MongoDB provides update operators, such as $set to modify values. Some update operators, such as $set, will create the field if the field does not exist.

updateOne() Method:
Updates a single document within the collection based on the filter.

updateMany() Method:
Updates multiple documents within the collection based on the filter.
