React

What is React?

React is a library that lets you assemble interfaces from small, clearly bounded components. Each one looks after its own state and appearance, and you nest them into views of any complexity. The model has proven itself over years and carries a gigantic ecosystem of ready-made components, tooling and knowledge. Its recent versions add Server Components and the React Compiler, which mean less boilerplate and automatic optimisation without you losing any control.

import { useState } from "react";

export default function Counter() {
    const [count, setCount] = useState(0);
    return <button onClick={() => setCount(count + 1)}>Clicks: {count}</button>;
}
