@bennyborn Unforunately you can't use the nullish coalescing operator (because stuff is outdated)

Also add spaces around the operators to pass the linter check, which counts as a test:

@icecream17 Thanks. Haven't looked into the checks since this morning.

Can we please have some specs on this PR?

I'm not quite sure what you mean by that. What do you need?

spec = test
(I don't know much about creating tests though - but I'd say that https://github.com/atom/atom/blob/master/spec/path-watcher-spec.js would be the file to change)

That makes two of us. I could try if I had any clue how the original problem occured in the first place but as stated in my first post I can only provide a fix, not an explanation :\

A test that sets up event.oldFile and event.newFile to be undefined (as input) and makes sure that payload.oldPath and payload.path (as output) are each the empty string '' rather than undefined should do it?

Edit: Seems kind of hard to test that level of internal detail in the spec file, because that level of hidden implementation detail stuff isn't exported from src/patchwatcher.js
