JSON.parse(JSON.stringify()) uses .toJSON when available. so should deepCopy

with JSON.parse(JSON.stringify()), we were cloning functions as undefined. Let's hope that isn't going to cause any any issues. 🤞🏽

LGTM. Please approve and merge at will.
And thanks for taking over and wrapping the PR up.

we might have the same issue here: the change makes semantic sense, but since we did not include the prototype in the cloned objects before, it's hard to know what side-effects this addition would have.
Can you please remove this?

we should definitely do this, just not in this PR.

It works with Object.create(null) as well and passing the tests but in my perf testing it fails and works only with Object.create(Object.getPrototypeOf(source))

maybe it's just assert.deepStrictEqual in nodejs

this works in both places Object.create(Object.getPrototypeOf({}));

Ok, it is just around 4% slower and still at the second place according to my perf test

isn't Object.create(Object.getPrototypeOf({})) same as {}?

probably, but with the object literal we ran into type issues again
