JSX makes your eyes bleed? Perhaps you would love E4X as well! Pretty much same concept:

    var someXML = <text>Why not?</text>;

Sadly, it's no longer supported in Firefox, but there are some ECMAScript variants still supporting E4X syntax, probably most notably ActionScript 3 as used in Adobe Flash.

Personally I love JSX, since it gives you all of the same power as template-based languages with virtually turing complete DSLs, but with JavaScript instead of a DSL. Not always as elegant, but almost always easier to understand.

My only real complaint is what JSX compiles down to. I think that it should either compile down to some data (like JSON data) or JSX should just be an alternative function call syntax. Instead, it compiles down to calls to React in most implementations (though usually, like with TypeScript for example, you can customize what it calls exactly.) The calls also vary depending on if the tag is lowercase or uppercase, since that's how React tells primitive tags apart from components. Frankly, a little ugly.
