Visual Studio Code is a powerful IDE, and my editor of choice while working on RxJS. They have some amazing debugging features, but I was having a really hard time getting it to work with TypeScript-based Mocha tests while working on the experimental branch of RxJS. The following is my…

TL;DR: No. I wasn’t, but now I am. I’ll have more time to support RxJS. RxJS will remain an independent OSS project, and will not cater only to Angular, but will continue to serve all of our many partners throughout the JavaScript community. I’ve been working at Google for a…

Once in a while I’m asked what I think about naming observables with an $ suffix. For example: const click$ = Observable.fromEvent(button, 'click'); Well, I personally could take it or leave it, but I know some of you can’t live without it. …
