Reactive Extension (Rx) libraries are everywhere, with the promise that they will make our code more declarative, less prone to bugs and overall simpler. But there is a price to pay for this simplicity – the Rx learning curve is notoriously steep. So before we jump head-first into yet another paradigm that promises to solve all our problems, let’s figure out what exactly there is to gain. In this talk we’ll look at some common front-end problems, and their proposed solutions in RxJS, and try to answer the question - does FRP really make our lives easier?
