The core of the React framework is a concept called state. It refers to a set of observable properties that can change based on user interaction. The state is stored in a component and is accessed via the component’s properties. If a component changes its state, the parent will receive the new value as a prop.

React is a scalable programming language, which means that it performs well in large programs. This is important if you need to build a complex application. It also has excellent performance compared to other JavaScript languages. This makes it a good choice for new and experienced developers. The language is also easy to learn and requires only a basic understanding of HTML and JavaScript.

Another great advantage of React is that it allows you to reuse components. This means that you don’t need to redraw the entire page every time you change the content. For example, if you want to make changes to the message that is displayed when a user clicks on a subscribe button, you’ll need to change its state, which you can do using React’s setState() method.

React also allows you to use props. Props are simply arguments for a JSX element in your React application. They look like standard HTML props and can contain a wide variety of JavaScript data types. They can be strings, functions, or even other React components.
