2. If Type(value) is Object or BigInt, then
a. Let toJSON be ? GetGetV(value, "toJSON").
b. If IsCallable(toJSON) is true, then
i. Set value to ? Call(toJSON, value, « key »).
3. If ReplacerFunction is not undefined, then
a. Set value to ? Call(ReplacerFunction, holder, « key, value »).
4. If Type(value) is Object, then
[...]
d. Else if value has a [[BigIntData]] internal slot, then
i. Set value to value.[[BigIntData]].
[...]
10. If Type(value) is BigInt, throw a TypeError exception
