I've been using overloaded operators as demonstrated in the second answer from here: How to use C++11 enum class for flags ... example:

#define ENUMFLAGOPS(EnumName)\
[[nodiscard]] __forceinline EnumName operator|(EnumName lhs, EnumName rhs)\
{\
    return static_cast<EnumName>(\
        static_cast<std::underlying_type<EnumName>::type>(lhs) |\
        static_cast<std::underlying_type<EnumName>::type>(rhs)\
        );\
}...(other operator overloads)

enum class MyFlags : UINT //duplicated in JS
{
    None = 0,
    FlagA = 1,
    FlagB = 2,
    FlagC = 4,
};
ENUMFLAGOPS(MyFlags)

...

MyFlags Flags = MyFlags::FlagA | MyFlags::FlagB;

And I've grown concerned that this may be …
