What is difference between v8::Object::Has() and v8::Object::HasOwnProperty()?

[kent williams]

If this is documented anywhere, I haven't found it.

What is difference between v8::Object::Has() and v8::Object::HasOwnProperty()?

for example:

var x = { HasThisProperty : true };

Both functions return true.

What would be a case where one was true and the other false?

Documentation is available in the header files, `Has` will return true whether the property is attached on the concrete object, or on the object prototype, while HasOwnProperty will return true only if the property is available on the object instance, but not on the prototype.
