napi_get_own_property_names

[dherman]

The property APIs include napi_get_property_names() for doing what I think is roughly equivalent to a for-in loop to collect all enumerable property keys, and napi_get_all_property_names() for collecting all property keys whether enumerable or not.

But AFAICT there's no API for doing the equivalent of Object.getOwnPropertyNames(). This one, especially in combination with napi_get_prototype, actually makes for a more powerful primitive, since you can incrementally crawl the prototype chain looking at the properties of one object at a time.

I imagine this one wouldn't be too hard to implement, and I suspect the design is fairly straightforward too: naming conventions strongly suggest napi_get_own_property_names by analogy to the corresponding JS API, and the behavior would simply be the same as 15.2.3.4.

Do the key_mode and key_filter inputs to napi_get_all_property_names() do what you need?

Oh! I completely misread the docs for napi_get_all_property_names(). I'll close the issue, thanks!
