State management is a critical part of app development but is often done unsystematically. Redux helps you manage state more efficiently, leading to JavaScript applications that behave more consistently and are easier to test. This course starts off with a practical introduction to Redux and how it fits into the JavaScript ecosystem, including the React library. As you move through the course, you can learn how to use Redux and work with JavaScript ES6/7, reducers, firing actions, thunks, and selectors. Instructor Richard Gill spends the final chapter using these Redux features in a real-world application—a messaging board similar to Reddit. By the end of the training, you will be able to apply all the concepts to a real project and understand how Redux can dramatically simplify the development of any JavaScript application.
