I hadn't heard about JSX before so I went to your link to check it out. This is just one of the most off-putting introductory statements I've ever read:
JSX is a JavaScript syntax extension that looks similar to XML.
Don't we all hate XML? How can you possibly even go on reading about this technology further if it's introduced like that.
XML is still used as a the standard for building layouts - on the web and on Android, and probably many other places. It can be much more readable than code for nesting components.
I believe people hating XML has more to do with using XML as a data transfer format, right? I'm happy using XML for Android layouts but can't imagine using it as a replacement for JSON - which I think is where most of the hate comes from.
XML is fine. XHTML is XML, after all. The issues with XML are the kind of XML that is often created with it, with namespace nightmares, endless embedded tags, etc. etc.
But if you're using XML to basically make a variant of HTML, it's great.
