React, Redux and Immutable.js: Ingredients for Efficient Web Applications (Publication)
https://www.toptal.com/react/react-redux-and-immutablejs
Unlike most front-end web frameworks, React's aim is to solve the various challenges of building user interfaces that rely on changing data. Although React is a simple JavaScript library and is easy to get started with, it is still possible to misuse it in ways that deny the web app from reaping the benefits that React has to offer. In this article, Toptal engineer Ivan Rogic demonstrates the synergy of React, Redux and Immutable.js, and shows how these libraries together can solve many performance issues that are often encountered in large web applications.
