React meaning

React definitions

React is a popular JavaScript library used for building user interfaces. It was developed by Facebook and released in 2013. React allows developers to create interactive UI components efficiently.

React uses a component-based architecture where UIs are divided into small, reusable pieces. These components manage their state and can be easily composed to build complex interfaces.

Virtual DOM

One of the key features of React is its use of a Virtual DOM. Instead of directly manipulating the browser's DOM, React creates a lightweight representation of the DOM in memory. When changes are made, React calculates the most efficient way to update the actual DOM, resulting in better performance.

JSX

React uses JSX, a syntax extension that allows developers to write HTML-like code within JavaScript. This makes it easier to create and visualize components in React applications.

State Management

React provides a simple way to manage the state of components. By using the setState method, developers can update a component's state and trigger a re-render of the UI.

In conclusion, React is a powerful library for building interactive user interfaces. Its component-based architecture, use of a Virtual DOM, and JSX syntax make it a popular choice among developers for creating modern web applications.
