Understanding Javascript Generators

If you are a JavaScript programmer and you don't like callbacks you should watch this to see the great new alternative for asynchronous programming.

This screencast will show you how to create and interact with generators and your programming life will be better!

Excellent, clear explanation. Thanks!

I agree that the generator function itself is simpler than callbacks, but I feel like that runner function put back in all of the callback complexity and then some. Every example I've seen so far for using generators looks like they don't alleviate complexity, but rather relocate it to another function. I'll admit though that JavaScript isn't my primary development language, so it may just take me using them in one of my toy projects to really see their value. Maybe my problem is that I already write my callbacks to look a lot like generators, but without the ability to yield control or maybe it's just the fact that generators seem like they'd be most useful in more complex situations than the simple examples used in tutorials. Either way, thank you for this tutorial series.

Wonderful.. Thanks.
Does the runner need to recursive? Will node will have a problem if we use something like while(!result.done) ?

Thanks. Very useful and understandable

4:48 you are requiring (./weather), why don't you use

import weather from './weather',

I'm aware your video is 2years old, but as you demonstrating EC6, I though it would be nice! Nice demo tho!

I remember having issues with local before and I’m not sure who it was

[audreymciver]

There is a bug in weather, check for remote acess in weather

[audreymciver]

That’s because someone is stopping me from accomplishing what I need to do. I do not want to be controlled
