This is a dubious claim, since JSX is limited to expressions. If you ask people for “a conditional in JS”, they’ll very probably go for `if (…) { … } else { … }` first, not `… ? … : …` (if you can even rewrite it as a ternary). Same deal with loops: you’re limited to expressions, so you can’t use the normal way of writing a loop (and this regularly leads to mild contortions as you deal with iterables of diverse types). Therefore I’d tend to (qualifiedly) describe JSX as doing its own thing too.
