Course Outline

React is a JavaScript library for building user interfaces. It simplifies complex arbitrary DOM manipulations by using a "virtual DOM" and its reconciliation diff algorithm, allowing you to easily transition your DOM into any arbitrary state, regardless of the current state. React implements oneway reactive data flow which reduces boilerplate and is easier to reason about than traditional data binding. Redux takes care of application architecture implementing Flux – a pattern Facebook uses for building client-side web applications.

It complements React's view components by utilizing a unidirectional data flow and managing the state of your application. Learning React and Redux will put you at the very front of the modern web development industry, while also making your new skill relevant for mobile development using ReactNative. This course will get you up and running with the essentials of React components, and creating systems architectures with Redux. You will be able to build scalable apps that run in a browser, then leverage this knowledge to build native Mobile or desktop apps. Whether you are new to React, or if you've started learning it already and need a thorough understanding of React.js & Redux - this course is the leap forward you are after.
