I’ve been wondering: instead of fixing typeof, wouldn’t it be simpler to extend
instanceof, by introducing new types:
- ReferenceType: to check whether a value is an object. Currently, objects such
as Object.create(null) and Object.prototype are objects that are not instanceof
Object.
- ValueType: for primitives and possibly future value objects.
- PrimitiveBoolean: for primitive booleans, same as typeof x === 'boolean'
- etc.
Should there ever be guards in the future, instanceof MyGuard would also make
sense.
