Huh, I've never seen return void draft.count++
before :D Surprisingly enough, it's syntactically correct.
Ah, it's actually in README. Looks like a typo to me, should be without that void
if anything.
Either way, with Immer you don't need to be returning anything, just mutate values and done.
The return
in reducer is just for convenience because of the switch
so you can exit that specific case. Without return
or break
it would fall-through to the next case.

@mweststrate you're right, my bad.
Like @FredyC suggested, not returning anything in the reducer function is fine. I didn't know that.
FWIW:
return void state.isOpen = true;
TS will underline =
and says ';' expected.
If anyone wants to still use void, you can do:
return void (state.isOpen = true);
But again, this works perfectly fine too:
state.isOpen = true;
return;

It would be good to update the readme to explain this.
