   Yes. Some popular promise polyfills totally trash the performance of "native" promises. I don't quite remember which ones. Needless to say, Posterus also compares very well in this field.

   Interesting! This must be new. Bluebird didn't have upstream cancelation last time I checked. Now it might actually be viable. Should update the readme. Thanks! Unfortunately it's still not viable in the browser due to its size, p

   Posterus provides coroutines just for that: https://github.com/Mitranim/posterus#routine Posterus coroutines are similar to async/await, but cancelable and free of `await`'s race condition problem (promise ca

   Negative. The scheduler is an optimisation. The alternative is to rely on VM scheduling using `process.nextTick` or `setTimeout` for every new async operation, which involves mandatory allocations and possibly other overhead. Using a custom

   Actually never heard of wisp. There's so many lispy dialects, smaller ones tend to get overlooked. I don't think I can get involved with another compiler at this point — got a bunch of other libraries underway, which have even mus

    Curious how Node isn’t even mentioned. Interesting how many years until it catches up.
