The data that was joined by the query will be the first element in the grades array. To join two collections, we use the $lookup operator, whose syntax is defined below: In MongoDB’s JOIN operation, the goal is to connect one set of data to another set of data. If documents are part of a “joined” collection, the $lookup (Aggregation) function will return documents in the form of a subarray of the original collection. $lookup(Aggregation) creates an outer left join with another collection and helps to filter data from merged data. We can join documents on collections in MongoDB by using the $lookup (Aggregation) function. To resolve this problem, we introduce the JOIN concept, which facilitates the relationship between the data.
