Thank you so much for the support, it means a lot to know that I can count on people when I have no clue what I'm doing.

@lezanardi function setEnumerable(object) { let private = {}; for (let key in object) { Object.defineProperty(private, key, { value: object[key], enumerable: false, writable: true }); } return private; } Will return the passed object with all the items non-enumerable.
