Clone and Performances ?

[jeremieca]

Hello,

Is paperwork clone all objects or just when there is too much fields ?

For example if I have this schema

var schema = { age: Number };

And this data

var data = { age: 20, firstname: 'Jean' }

The output will be :

{age: 20}

So, if I well understand, you have created a new "cleaned" object during validation.
But what happened if in data there is no extra fields ? Is object also cleaned ? What is the performance cost ?

Thanks.
