ClojureScript compiles down to JavaScript, so yes, it is entirely possible to spell the same buggy jQuery site you would in regular JavaScript but with the parentheses on the outside and it will solve no problems for you. I don’t think it’s reasonable to say eg reagent does not solve any DOM problems. Similarly, CLJS uses the same source map standard as every other JS targeting language, so you can debug in CLJS with the tools you already use just fine.

Their negative experience is based on facts not in evidence so I can’t really comment specifically. The StackOverflow community survey results suggest their experience is at least unusual.
