Yeah, the conversation was about vanilla js, and this links to that. We
want  `Reflect.create` to be a solution instead of writing  `var
DefaultValue = DefaultValue || SomeOtherValue`. That is what the medium
article was about. And that was what the medium article was about, of which
Brendan was agreeing too. The rest of the discussion was about shaping the
code into a proposal, of which we didn't manage to do.

In order for you to fully understand the context I have copy+pasted from
MDN so you can stop arguing of how I wrote "it is not an object". In terms
of how this is not an object, is that is doesn't give us a constructor or
prototype(?) and it behaves statically in that matter.


Unlike most global objects, Reflect is not a constructor. You can not use
it with a new operator
<https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/new>
or
invoke the Reflect object as a function. All properties and methods of
Reflect are static (just like the Math
<https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Math>
 object).

I guess that this is repetition, but there's no wrong in saying this again.
IMO. was bad typed by me there. By logical instance I mean that it
should  remove
code with logical operators, which uses the existing variable, to reassign
it with an logical operator as a fallback value.

About the Reflect instance, that is wrong, should be revised, indeed. I
used it as outside JavaScript context. And no, Reflect doesn't become a
constructor, both of us know that, so I don't know why you brought it up.
Fail in this context means that the object returned with an error, null or
undefined. I disagree. People understand the relationship between error,
null and undefined as similar, meaning if things go south, this is where we
put our try/catch as an function object.

The examples are to show the use of undefined without the "proposal". ( It
chronological, so last example would be natural in this use case ) .

To Bergi:

Yeah, it serves its purpose, but I think that   `var value = value ||
"another value";` is bad as opposed to how I'd tackle it with Reflect. I
always think that you don't need to write things as-they-are in forums
where people have worked with JS quite some time. I tried to explain why I
mean that this isn't a real object by saying that it doesn't contain
prototype or constructor and thereby people got the analogy. Often when I
say things are not things, as by object is not objects, I assume people
manage to reason without having to pin facts straight into their faces.
Often I and people find that disrespectful( people try to teach you like a
kid). Anyways, Reflect cannot be created as Object.Reflect, and that is
what I mean by you having to assign it like:  `var Value = Reflect.create()
 `

I'd like us to make a thread/ issue on the repo, so we avoid spamming
people if that is fine? Also, if you have any other questions regarding how
things are written, please, do file a PR, I bet you are better at
explaining things in text than I am. :)
