To update a nested array in MongoDB, you can use the $ operator to specify the position of the element in the array and the $set operator to specify the new value for that element
$push is an operator in MongoDB that is used to add an item or items to an array within a document.
$pull is used to remove an item or items from an array that match a specified condition.
$pop is used to remove the first or last item from an array.
$addToSet is used to add an item to an array only if it does not already exist in the set. These operators are useful for modifying array values in a MongoDB document without overwriting the entire array.
