Thanks! Yes when we asked people what they used to prototype, we got the weirdest answers. Replit seems very heavyweight, and isn't local (always feels worse).

For non-npm things, we heard that a lot of people open up a browser console to use it as a REPL. I think we can do better, hoping Srcbook can cover these use cases well. The Markdown is a really neat idea borrowed from Livebook. It allows for really good diffing if you want to version control them, and makes reviewing diffs easier. As a bonus a lot of things can read markdown and render it nicely for you.
