React Components | React JS Tutorial for Beginners – Part 2

In this tutorial, we will continue our exploration of React by focusing on React components. Components are the building blocks of React applications, and understanding how to create and use them is crucial for anyone getting started with React.

What are React Components?

React components are reusable pieces of UI that can be composed together to build complex user interfaces. They encapsulate both the UI and the logic of a particular part of the application, making it easier to manage and maintain the codebase.

Creating a React Component

To create a React component, you can use either a class component or a functional component. Here’s an example of a simple functional component that displays a greeting:

        function Greeting(props) {
          return 
Hello, {props.name}!
;
        }
      

Using a React Component

Once you have created a component, you can use it by including it in another component’s render method. Here’s an example of how you can use the Greeting component:

        function App() {
          return (
            

              
              
            
          );
        }
      

Component Props

Components can receive data from their parent component using props. The props are passed as attributes to the component when it’s being used. In the example above, the Greeting component receives the name prop and uses it to display a personalized greeting.

Conclusion

Understanding how to create and use React components is essential for anyone looking to build applications with React. In the next part of this tutorial, we will discuss more advanced concepts related to React components, such as state and lifecycle methods.
