i think the best thing about yield* next
is that now next
is explicitly a generator.
from compose.
that's not even remotely enough of a gain to worry about IMO, add one console.log() per request and you take a bigger hit. If anything we could improve co's perf by adding a shared scheduler but not a huge deal really. I don't like the context switching between yield and delegation
from compose.
i'm not worrying about it :P it's just free to me.
from compose.
it would kinda almost be nicer if javascript would just auto-delegate when you yield a generator, maybe make yield *
the inverse haha.. meh
from compose.
i wish there were no stars anywhere

that too

"i wish there were no stars anywhere"
That really describes the sentiment. :)

Is there any significant drawbacks when using yield* like memory consumption or cpu usage?
IMO it should be not too hard, and it also has less chance to break something. So hopefully it will be finally changed.
from compose.
there really isn't any downside, but it's probably not worth the cognitive overhead for new beginners, especially with async/await
coming along.
