Syllabus

    • In this introductory module, you'll learn about what React is and where it is used. You'll also learn how to set up your coding environment so that you have as productive a learning experience as possible. So, the purpose of this module is to understand the what and the why, and to get set up for the modules that follow.
      Components are one of the foundations of React. In React, everything revolves around components. You'll learn how to build components, how to structure and customize your React projects, and how to compose layouts by importing components into other components.
      You'll learn about passing data from one component to another. You'll learn about JSX syntax in React and how to use it to structure and style your components.

    • The second module of this course deals with working with events and errors in React. You'll learn how events work and how you can handle them in React. Handling events can sometimes get a bit tricky, so you'll also learn about dealing with errors related to events in React.
  • Navigation, Updating and Assets in React.js
    • In this module, you'll learn about routing and navigation in React. You'll learn how to render partial views and how to update routes in your React apps. You'll understand how assets are used, bundled and embedded.
  • Your first React app
    • This module is focused on a practical mini project of building a calculator app in React. Upon completing this module, you'll have coded your own mini project in React, as a starting point for building your React portfolio.
