In this chapter, we are going to learn how to implement React components, how to assemble multiple components into one, and how to manage their internal states. We will explore React component implementation by building a simple application. This application will be implemented step-by-step, in order to put the outlined concepts into practice.

By the end of this chapter, you will be able to:

• Create basic React components
• Use JSX to define a component's markup
• Combine multiple React components in order to create complex UI elements
• Manage the internal state of React components
