Redux for React using JavaScript/ECMAScript
Overview
Redux is a predictable state container for React. As React applications become more complex, developers often find a need for more structure around the data or state they are managing in their application. The Redux JavaScript library provides an elegant solution for this need.
This Introduction to Redux for React using JavaScript/ECMAScript training teaches developers the skills they need to immediately use Redux in their React applications.
Note: This Redux class can also be taught using TypeScript.
Objective
- Understand state management including when it is needed and the various alternatives
- Utilize Redux to manage the state of the application.
- Use React and Redux together
- Implement React and Redux best practices
- Write unit tests for React using Jest and React Testing Library
