No more function color! Yes one-shot delimited continuation!
What the hell?! Well... I really recommend that you read this blog post by Dan Abramov explaining algebraic effects - and how it could be very useful on our JavaScript code: https://overreacted.io/algebraic-effects-for-the-rest-of-us/
This project is a runnable POC with a Babel's "plugin", so you could write some code and taste this new concept in JavaScript. Its features, syntax, and goals are very inspired by Dan Abramov's blog post mentioned above. In short, with algebraic effects, you could separate what from the how and have fewer refactors.
What do you think? Would that be a good feature for JS?
