How to debug/log useful information inside immer callback?

If you serialize / de-serialize the draft, the output will be a plain JavaScript object and will appear as such in the console.

console.log(JSON.parse(JSON.stringify(draft)))

Immer 7+ has current() for this purpose. So, you can do this:

import { current } from 'immer';

console.log(current(draft));
