Class and value internal properties are always exists for primitive types (e.g. Boolean, Regex) so they can be stored right after the object. This improve property access (since internal properties are searched by a slow linear algorithm) and reduces memory consumption, since only 8 byte is allocated for these two properties instead of 16 which is the size of a property pair.
