Building with Blocks
React's component-based architecture allows developers to break down complex UIs into small, isolated pieces of code. This modular approach has several key advantages:
- Reusability: Components can be reused across different parts of an application, or even in different projects.
- Maintainability: It's easier to update and debug small, self-contained components than a monolithic codebase.
- Scalability: As an application grows, a well-designed component library can be easily expanded to accommodate new features.
function Welcome(props) {
return <h1>Hello, {props.name}</h1>;
}
The simple function above is a valid React component. It accepts props
(properties) as an argument and returns a React element. This is the fundamental building block of a React application.
