ES6 promises and generators for coroutine -- Seattle JavaScript Workshop / Jelly

Each month, we pick a topic for round table discussion, or hacking session on a JavaScript technology.

Send us JavaScript topics or technologies that interests you.

This week, we'll be talking about using promises and generators, both features of the upcoming ECMAScript 6, to manage asynchronicity. Both features require either a beta release of the browser or a flag enabled, but there is a shim for Promises available.

To practice our generators, we'll be trying to make a homegrown coroutine wrapper, similar to co. By combining promises and generators, we can manage asynchronicity in a very similar fashion to languages with real async/await keywords, like C#.

    Hey everyone, the cafe seems to be closed. I'm waiting outside, and when we get a few more people we'll pick a new location nearby.

    Topic turned to Angular.js and reactive.js? being a smaller utility that do the binding, but still useful without taking over your whole app.

I started the group because there wasn't any other type of group like this. I've met some great folks in the group who have become close friends and have also met some amazing business owners.
