What is React JS?
React JS is a JavaScript library for building user interfaces, especially interactive web applications. It was originally developed at Facebook and is widely used for creating component-based front-end applications.
Why React is Popular
- Component-based architecture
- Reusable user interface components
- Declarative programming model
- Efficient UI updates
- Large developer ecosystem
- Strong community support
Example
function Welcome() {
return <h1>Hello React!</h1>;
}
React applications are built by combining reusable components into complete user interfaces.
