Iterating over non-enumerable properties

Question

I have used Object.defineProperty and enumerable: false to define a few properties on a config object. There is however one place in my module where I would like to iterate over the non-enumerable properties as well as the enumerable ones. Is it possible to do this without keeping a list of property names elsewhere?

Answer 1

I guess you could use getOwnPropertyNames which returns properties, enumerable or not.

From the docs:

Returns an array of all properties (enumerable or not) found directly upon a given object.
