$Min Operator

The $min operator updates the value of a field to the specified value if the specified value is less than the current value of the field.

In the above collection, the requirement is to update the value of age to 27 if the value of age is less than 27. So, the query is: -

db.mycollection.updateOne({ _id: ObjectId("6597b8a02695219f3c55e481")},{$min:{age:27}})

$Max Operator

The $max operator updates the value of a field to the specified value if the specified value is greater than the current value of the field.

Consider the following query: -

db.mycollection.updateOne({ _id: ObjectId("6597b8a02695219f3c55e481")},{$max:{age:29}})

In the above collection, the requirement is to update the value of age to 29 because the value 29 is greater than the current value of age i.e., 27.
