$inc

Update records by incrementing the value of a numeric column. The $inc method is used to increase the existing value of a column by a specified amount, typically used for fields like counters, quantities, or numeric metrics that need to be updated incrementally.

await Member.$update({
    $where: { 
        age: { 
            $eq: 16 
        } 
    },
    $update: {
       $inc: {
        age: 4
       }
    }
});
