Scales very well.

Immutable data pairs great with REPL.

Because data are immutable, you don't need to care about where that data come from and where it will go. Just focus on what you need to do with that data at the point you work.

Everything is localized due to immutability.

I’ve started learning clojure recently and I haven’t quite grasped the REPL yet. I really like it, but so far the type of feedback it provides feels similar (and sometimes inferior to) a static type system. I mostly use it as a tool for answering “wait what data does this return?” And of course trying functions as I’m building them.

Are there any tricks or habits you learn with the REPL that go beyond what a static type system gives you?
