Undefined value #54

Closed josinaldobarbosa closed 4 years ago

josinaldobarbosa commented 4 years ago

should that be undefined?

Original: [ { _id: 123, id_content: 111, id_category: 22 } ] New: [ { id_content: 111, id_category: 22 } ] detailedDiff/diff: { added: {}, deleted: { '0': { _id: undefined } }, updated: {} }

Yes, this is the way this module works, it outputs the current value, since _id no longer exists, its current value resolves to undefined.

Yep, I think that's the expected behaviour. The readme deletedDiff example works the same way.
