Functions inside/outside proxy: which idiom is better (and why)?

[rodrigocfd]

Functions outside proxy:

export const store = proxy({
	count: 0,
});

export function inc(): void {
	++store.count;
}

...or functions inside proxy:

export const store = proxy({
	count: 0,

	inc: (): void => {
		++store.count;
	},
});

Which idiom is better (and why)?

Alternatively, this works too:

export const store = proxy({
  count: 0,
  inc() {
    ++this.count;
  },
});

All of them are good, but only the first one is capable of code splitting, I suppose.
