Build Reactive Websites with RxJS
Upgrade your skill set, succeed at work, and above all, avoid the many headaches that come with modern front-end development. Simplify your codebase with hands-on examples pulled from real-life applications. Master the mysteries of asynchronous state management, detangle puzzling race conditions, and send spaceships soaring through the cosmos. When you finish this book, you'll be able to tame the wild codebeasts before they ever get a chance to wreck your day. The front-end world can be fraught with complexity. The RxJS library offers a solution: Observables. Observables merge other JavaScript asynch mechanisms such as callbacks and promises into a new way of looking at data. Instead of dealing with objects and keeping track of their state, Observables view asynchronous events as a stream. RxJS provides you the tools to manage, manipulate, and process Observables to simplify and speed up your front-end applications. Never fear, you're in exactly the right place. Don't worry about ...
