hakk is a new REPL-based tool for developing Node.js programs. hakk runs your .js source files, and updates your program as it runs whenever you make a change. Unlike the built-in node repl, hakk lets you re-define consts, functions, and class members while your code is running. It works with any code editor.

I would love to get feedback. Do you find this tool useful? What improvements would you like to see?

Is this inspired by the recent post "My Kind of REPL"[0]? :)

I hadn't seen that post, but it's great!

This project was largely inspired by my experience with Clojure, and my wanting to have a similar capability when writing JS code.
