>feels so uninspired and without thought of the design, in my opinion.

Thanks for feedback! I assure there wasn't a lack of thought, in fact we discussed this for several weeks before even beginning to implement this. Your proposal was also considered but it doesn't bring anything over <>, whereas * already has a meaning in JS related to generators. It would be confusing to use it here for a different purpose.

FYI, <> is not original. As mentioned in the post, it has prior art. It already went through standardization once (in E4X). It has also been used for months (maybe over a year) in ReasonML, and its users reported really enjoying this syntax.

You may not like it but it doesn't mean we haven't given this any thought. :-)

Yes, technically if the empty tags do suffice, then the asterisk brings no additional value, and it would be potentially confusing to use a character that already serves a purpose in Javascript, although I doubt it since JSX tags don't support generators as an attribute or name. You could replace the asterisk with a different character in that case. My main point is that the empty tag feels, well, empty and made without a real purpose, in part because it's just so foreign compared to HTML (which is what JSX is based on?) as this kind of thing is never found in HTML. While I'm sure that there wasn't a lot of discussion within the React team about this, the inclusion of at least a single character, whatever that would be, would make it feel like it was actually designed properly, and I would also argue that adding something to make the tag feel nonempty would actually have a value (to make the tag explicit and not confusing).

I don't necessarily buy the prior art arguments too because E4X was barely used even though it was a standard and is now deprecated, and ReasonML is pretty specialized and much less popular, as well as has a different set of users, than React. If you had told me a product in the same category as React, like Angular, Vue, Ember, Ractive, etc., used that syntax, I would be much more receptive.

Not currently, but we do have some plans regarding do-expressions, generators, and JSX. So * might get a meaning, even though not in attributes but children.

I think most React users in practice don't touch HTML that often. JSX has quite a few differences with HTML, and we don't really plan to bring it closer to HTML in the future. It is more important to us to make JSX pleasant and convenient to everyday React users than it is to have 1:1 mapping to every HTML concept.

>ReasonML is pretty specialized and much less popular, as well as has a different set of users, than React.

I would argue that people using ReasonML today are the same kind of early adopters (and often even the same people) that started using React four years ago when the ecosystem didn't exist (and shaped that ecosystem). I trust their judgment.

By that logic, we could dismiss React when it came out, because it was not like anything else :-) Give this syntax some time. It felt odd to me at first, after living with it for a few months it feels very natural. I'm sure you'll get to like it eventually too. At that point it might feel odd that other libraries don't provide this syntax.
