Diff and merge functionality in javascript

[Koen]

Hi,

Is there a way to get a diff and merge that diff into an instance of a message?

E.g. I saw there is a static method on Message class 'difference', that returns a new message instance with the fields of param2 that are not represented in param1.

Any existing methods that can merge the diff?

With kinds regards

Can you use MergeFrom?
