<b><p>DESCRIPTION</p></b><p>A growing flood of data is aimed at JavaScript applications, and they</p><p>need be ready for it. As more and more data is received, applications</p><p>must scale to stay operational. There¿s also the problem of latency</p><p>when data has to be fetched from remote locations. RxJS, or Reactive</p><p>Extensions for JavaScript, is a library for transforming, composing,</p><p>and consuming streams of data. RxJS combines reactive and functional</p><p>programming to give an extensible, asynchronous event handling</p><p>system for JavaScript.<i></i></p><p></p><i>RxJS in Action </i>gives readers the development skills they need to create <p>reactive applications with RxJS. This book is full of theory and</p><p>practical examples that build on each other and help readers begin</p><p>thinking in a reactive manner. The book begins by teaching the</p><p>fundamentals of functional programming, and dives in to the basics of</p><p>RxJS and what it means to be reactive. Ne
