Oh yeah, jvm. If I were to go java, I'd use clojure 

 I do like functional programming but dynamic langs still scare me for large apps 

 I'm afraid now that I've embraced types I won't be able to go back 😢 

 Kotlin supports types. And it has proper null checks unlike Java 

 I used it for a web app a few years ago.

Was not good as frameworks like Svelte. But also was somewhat better than writing raw JS 

 Kotlin compiles to native :)
