JSX isn't HTML. Is it truly less cognitive burden to have a language that looks like HTML but isn't? With properties changed because they're reserved words? And with control statements from other languages supported inline?
If someone gave me a language that looks like Lisp but with car and cdr renamed to something else, is that really making my life easier?
What cognitive problem do you have? It's just syntax sugar to let you easily manipulate the dom tree. Generating dom nodes and intertwined logic becomes trivial when you have jsx. If u want a list u can do dataList.map(data -> SomeComponent); or do ifTrue ? Component1 : Component2; or even use a function to return conditionally with a switch.
JSX is not HTML because it need to blend logic and HTML seamlessly. React is not static site builder, it's an app builder. If your project doesn't need this sure go ahead. Otherwise are there much better choices?
