Proposal for a lightning talk at the Reactive 2016.
Keep calm and like/retweet it on Twitter and star this Gist to vote on this talk.
I work at Grammarly. We like React and happily use it in our applications. However, sometimes something goes wrong and bugs creep into the code. Here comes testing. It helps make us confident about the quality of our code.
Functional reactive programming (FRP) is very popular nowadays. The JavaScript community provides us with excellent tools like RxJS, Bacon, and Kefir. But, as we know, they have nothing to do with React. So how we can use the power of FRP in our React application? Using the correct state management, we can make friends with FRP and React and make our application truly reactive. In my lightning talk, I will talk about Focal
