How do you iterate over all methods in a JavaScript pseudoclass, regardless of whether or not they are marked enumerable?

Question

I'm trying to iterate over all methods in a JavaScript pseudoclass and can easily tell if something is a method or not with (obj.member instanceof Function), however I'm trying to include methods that may be hidden from a for...in loop via defineProperty with an enumerable flag set to false - how do I iterate all members of a pseudoclass, regardless of the enumerable value?

Answer 1

You can always use Object.getOwnPropertyNames, which will include non-enumerable properties as well. However, this will not include properties from prototypes, so if you are asking about "pseudoclass instances" you might need to loop the prototype chain with Object.getPrototypeOf.
