The basic structure of a React application consists of multiple components with logic and controls. These components can be reused throughout the application. Data flows from a top-level component, called an “App,” down to child components. React’s unidirectional data flow makes debugging errors easier and makes it easier to locate problem areas.

React JS is a powerful front-end development tool that makes the creation of interactive UIs a breeze. Its step-by-step approach and large community of developers make it easy to learn and create applications. As long as you have access to a web browser, React JS will give you a unified experience across different platforms.

React offers a number of built-in hooks, which are helpful for handling state, side effects, and other common scenarios. It also supports the JSX syntax for describing user interfaces. This allows you to write HTML structures within the same file as your JavaScript code, so you don’t have to write multiple lines of code for every interaction.

React JS can create a Virtual DOM (virtual document object) which is a copy of the real DOM. This virtual DOM is updated whenever a component changes. This eliminates the need for a full page reload and reduces the risk of layout trashing.
