How to list the properties of a JavaScript object?

Question

Say I create an object thus:

var myObject =
        {\"ircEvent\": \"PRIVMSG\", \"method\": \"newURI\", \"regex\": \"^http://.*\"};

What is

Answer 1

Use Reflect.ownKeys()

var obj = {a: 1, b: 2, c: 3};
Reflect.ownKeys(obj) // ["a", "b", "c"]

Object.keys and Object.getOwnPropertyNames cannot get non-enumerable properties. It's working even for non-enumerable properties.

var obj = {a: 1, b: 2, c: 3};
obj[Symbol()] = 4;
Reflect.ownKeys(obj) // ["a", "b", "c", Symbol()]
