I just want to compliment the OP on a very clear and comprehensive website at https://imba.io/ . It clearly explains (by showing and telling) what Imba is, why I should care, how it works and how to get started. The floating demo applications even work well on mobile. Rare to see this level of polish for these things.

I've noticed that some projects being complimented for having good docs come from CTOs (esbuild is another example). I'm hoping that by pointing out this little correlation, people might feel more inclined to spend more time on writing docs for their projects if they aspire to climb in the career ladder :)

I started working in node around version 0.8, before both native Promises and async/await. I worked with guys that started after async/await. The new guys just think of everything like it's synchronous. They don't understand Promises. They never look at code and think "I can run this in parallel with Promise.all and a reducer". They just await each thing one at a time. So, I'm not sure the async/await annotations are…

I'm new to NodeJS but it was my understanding that using await like that would help by not blocking the thread, leaving node free to process other requests.

  await slowThingOne();
  await slowThingTwo();

  await Promise.all([slowThingOne(), slowThingTwo()]);

lack of types and it used to be ignorant of perf in the generated code (creating IIFE unnecessarily)

Regarding types, you're right, though JSDoc can get you very far Regarding perf (performance, I guess?) - are you speaking of the single, global one? As CS takes care of variable scoping automatically, I think it makes a lot of sense (and is deactivatable anyway)

await won't block Node from handling other requests but it will block the thread that is awaiting. For example, these will execute one after the other (the "bad way"): await slowThingOne(); await slowThingTwo(); but these execute in parallel, awaiting until both are finished (the "good way"): await Promise.all([slowThingOne(), slowThingTwo()]);
