I just wanted to add that "dynamic" doesn't mean untyped or weakly typed. Clojure is a strongly-typed dynamicly-typed PL. Clojurescript compiler for example, in many cases can produce safer JS code than even Typescript ever could.

Out of curiosity, can you give an example of where ClojureScript is safer than TypeScript? I'm pretty far removed from the frontend world so this sounds pretty interesting to me.

This is a slightly expanded answer to your question, apologies for the external link, I could of course repeat here verbatim, but let's not increase entropy needlessly, right? https://www.reddit.com/r/Clojure/comments/1dyjwyo/is_it_easi...

Beware though, that there are today more than one flavor of Clojurescript, nbb for instance still acts just like JS in this regard.

This is exactly what I wanted...thanks!

The last time I did ClojureScript in serious capacity was for a school project in 2021, specifically because I wanted to play with re-frame and the people who designed the project made the mistake of saying I could use "whatever language I want".

It makes sense, but I guess I didn't realize that ClojureScript generates some nice runtime wrappers to ensure correctness (or to at least minimize incorrectness).

I guess that means that if you need to do any kind of CPU-intensive stuff, ClojureScript will be a bit slower than TypeScript or JavaScript, right? In your example, you're adding an extra "if" statement to do the type check. Not that it's a good idea to use JS or TypeScript for anything CPU-heavy anyway...

In rare cases, sure, it can add some overhead, and might not be suitable I dunno for game engines, etc., but in most use-cases it's absolutely negligible and brings enormous advantages otherwise.

Besides, there are some types of applications that simply really difficult to build with more "traditional" approach, watch this talk, I promise, it's some jaw-dropping stuff:
