What is Aggregation in MongoDB with example

Aggregation is a key operation in any database that allows you to process data records to get targeted results. With the help of aggregation, the users can combine several entities to form a single meaningful entity by grouping the data. The aggregation operations consist of several expressions that help to group the data for a meaningful output.
