Hopac VS c_playground

https://github.com/Hopac/Hopac is such an impressive piece of software. Too bad it never really took off like it deserved but with more popular competition like rx or just tasks/async (which is enough for most stuff) pretty unavoidable.

Found this article, it didn't even occur to me to look for a channel library in JS. This is definitely the direction to go in. Incidentally, Hopac is the most underrated of all F# libraries, just sayin'.

3) This third part is the hardest, and that is to get proficient at concurrency itself. For this I had to study various libraries like Rx, but what I settled on after a lot of experimentation was to first compile the various passes to streams of lazy promises. For languages in particular, they have a top down structure and what is needed is to employ a lot of diffing in order to reuse old results. The difficult part is to organize all of this. I can't praise a library like Hopac enough, but even with it, it still took me months to get a grasp on the way the editor support segments should be designed. At the time of writing, I am a day away of finalizing what will be the true design of the language server. It is not that the end result is complex, this latest redesign of the last 1.5 weeks is in fact significantly simpler than what I had before, but concurrency requires different design principles than sequential programming and getting used to the new domain takes an active effort.

GCD/libdispatch is a fantastic approach to concurrency and you can build and install support for non-Apple operating systems:
