[rattray]

Very interesting! Thanks for clarifying.

I've also done some work on Prettier in the past, so I'm curious about some details there too.

1. Do you plan to build a wadler-based formatter, similar to prettier? Will it be as opinionated as prettier, or based on a pluggable architecture? (I'll admit that I have yet to conceive of a viable way to make the latter work well).

2. Have you considered (or already built) an incremental parsing server for tools like the formatter? For example, when I add a statement at the bottom of the document, will it reparse the whole document, or be smart enough to notice that a change has been made that can use cached results for most of the AST? (I'm not sure if this is feasible for JS, especially for parsers that require line/col info).

In any case, I'll be following your progress with great interest!
