- Introduction In this section, we’re diving into the world of React components! Components are the core building blocks of a React application. Our friendly characters, Geek and Gal, will help explain components in a fun and easy-to-understand way. Let’s begin!
Are you ready to explore React components? 💡
Absolutely! What is a React component, though?
A React component is like a reusable piece of your app's user interface! They help you create dynamic and interactive UIs with ease.
- Introduction to Components
Components can be either functions or classes in JavaScript. They accept "props" as input and return a piece of the user interface as output.
What do you mean by "props"?
Props are short for "properties." They're like inputs you can pass to a component to customize its appearance or behavior! 😊
Here's a simple example of a functional component in React:
function Welcome(props) {
return <h1>Hello, {props.name}!</h1>;
}
Ah, I see! So a component is just a function that takes in props and returns some UI elements!
You got it! And to use a component, you just write it as a custom HTML tag, like this:
<Welcome name="Sara" />
Oh wow, it looks like an HTML tag, but it's actually a React component, right?
Exactly! And the best part is that you can reuse components just by changing the props! 🎉
- Conclusion React components are the foundation of your app’s user interface. They can be written as JavaScript functions or classes, and you can pass them props to customize their appearance or behavior. Understanding components is essential for creating dynamic and interactive React applications! 🚀
