The problem I see with clojure, isn't it missing autocompletes? You work with JVM/typescript libraries, but your editor isn't smart enough to pull types from those into clojure. That slows you down tremendously.

No. When working with JVM/typescript libraries you have their autocomplete information. If you need method autocomplete scoped to a type you can use the `..` macro for more concise call syntax: (ns my-project.core (:import (java.util ArrayList Collections))) (defn example [] (let [list (ArrayList.)] ; ArrayList constructor can be autocompleted (.. list (add "Hello") ; The .add method on ArrayLists will be autocompleted (add "World") (add "Clojure")) (Collections/sort list) ; The Collections.sort method will be autocompleted list)) this other form will a also autocomplete everything after the dot (.) to call a method on an object: (.toUpperCase some-str) but the trick with this arrangement is to write that variable some-str first, then if you write . in front of it the autocompletes will be relevant to that object. But I gratuitously used threading macros like .. or -> to make it match java-style code (in other words: (-> some-str (.toUpperCase))).

  That's cool, I had no idea. In clojure itself I suppose you eval code and then get autocompeletes from the repl output? -- I mean for stuff with no types

    Autocomplete also works for the functions and vars in the namespaces. You don't really use methods in Clojure unless you're doing interop with Java or JS.

I use Emacs with Cider+clojure-lsp, and the autocomplete/refactoring tools are super good.

Autocomplete works for me with jvm imports

As a Clojure editor tool smith it pains me that this is the case. Especially for ClojureScript where I spend most of my time. I really want to fix this. For JVM interop, I think Cursive (IntelliJ Clojure plugin) is smart enough to help with autocompleting Java libraries.

  Yea, Cursive is the best by far for doing Java interop. It is really good.
