Feature Request - Diff by a value

[gperdomor]

Current behavior:

Now a diff function is provided which work fine when elements are plain, but what about arrays of objects?...

Expected behavior

I think that something similar to https://lodash.com/docs/#differenceBy should be provided by this tool :D

I looked at the code and it's possible with a third param, seems like the docs needs to be updated
