Is there a possibility to use immear as one-liner?

πββ Question
I personally don't like this code taking 3 lines instead of one
const newRecords = produce(scheduleRecords, (draft) => {
draft[index] = updatedRecord
})I would like to have
const newRecords = produce(scheduleRecords, (draft) => draft[index] = updatedRecord)but I got a TS error
TS2769: No overload matches this call.
The last overload gave the following error.
Type 'Partial<Record>' is not assignable to type 'ValidRecipeReturnType<WritableDraft<Partial<Record>>[]>'.
Environment
v10.0.2
We only accept questions against the latest Immer version.

Of course, you can achieve that with the comma operator of javascript. For instance:
import { produce } from "immer";
const defaultMySubState = {
someString: "foo",
}
const newRecords = produce(defaultMySubState, (draft) => (draft["someString"] = "updatedRecord", void 0))But to have better readable codes, I will never use this shortcode in a team project π. I think we should avoid it.
@mweststrate @lyluongthien thank you guys
To clarify my previous message, no comma operator is needed here, since void can be used directly as operator. So it'd become:
const newRecords = produce(scheduleRecords, (draft) => void draft[index] = updatedRecord)
