KeyTakeAways About MongoDB $pull Operator
- The $pull operator in MongoDB provides a way to delete specific elements from Arrays and helps in data manipulation and customization.
- In the $pull operator, if you specify the <condition> and the array contains the embedded/nested documents, then this operator applies the <condition> as if each array item were a document in a collection.
- If you specify a <value> in the $pull operator to remove in an array, then this operator will remove only those items in the array that match the specified <value>. Here, the order must be the same.
- If you specify a <value> in the $pull operator to remove a document, then this operator will remove only those items in the array that have the same fields and values. Here, the order of the fields can differ.
- You can use this operator with methods like update(), findAndModify(), etc., according to your requirements.
