I use repls a lot, both when I used clojure and now when I mainly use python. The reason for me is language exploration. I write my program and don’t always know how to do something and the internet is ambiguous. With a nice repl I can rapidly iterate trying different things and doing micro in-situ experiments to explore and understand how the language (or library more frequently) works. It’s very edifying.
