`napi_get_property_names` is buggy in node 10.19

[artemp]

napi_get_property_names(_env, _value, &result);

erroneously returns Number type when property name has only digit literals e.g '123'

This has been fixed in node >=12 (tested 12.16.1, 13.12.0)

@artemp nice catch. Can you try to track down what change in node core fixed what you are seeing? Also, could this explain #40 ?

[springmeyer]

Also, could this explain #40

This btw seemed to me like a v8 behavior rather than node core or Nan related, but I'm not positive.

[artemp]

yep, #40 looks related. I'll investigate further and add workaround in our code if required.

[springmeyer]

thanks @artemp - I feel pretty good about #40 as a workaround, but let me know if you see a better one.

[artemp]

@springmeyer - re: #40 fix - ideally we shouldn't use v8 methods from N-api module.

[springmeyer]

ideally we shouldn't use v8 methods from N-api module.

Ah, good point.

Fix

Napi::String Napi::Value::ToString() const;

^^ Returns the Napi::Value coerced to a JavaScript string.
