“WTF is JSX” is a good primer on what JSX is, even. I recall the first time I saw JSX I was a bit confused and it gave me the heebie-jeebies. “What’s that template doing in my jobblescript?” I moaned. But once I understood it I came to appreciate that it really serves to modularize and un-obfuscate UX code.
Besides, all templating languages suck.
