Generators aren't for concurrency.

When a generator runs, it runs in the same thread as the caller. The
order of execution is sequential and deterministic, and never
concurrent. Unlike system threads, a generator is only ever suspended
at points marked by yield in its body.

Re: About generators

2015-05-14 Thread Jeremy Martin 
Hey (author of suspend here): this post was an earlier attempt I had an
explaining some of the concepts involved:
http://devsmash.com/blog/whats-the-big-deal-with-generators

It covers some of the basics, like, what iterators are, how generators
relate to iterators, how generators enable "suspended" execution within the
context of run-to-completion semantics; etc. Hope it helps!

Hi,
I have used simple generators but there seem to be some advanced 
usages.  I came across these git references from another post and I have looked 
at the code. What are some articles that explain these concepts for JS

Thanks. What is the underlying concurrency framework when we use generators for 
concurrent workloads ? Does it depend on the particular VM ?
