React js training in kukatpally

ReactJS is an open-source JavaScript library for building user interfaces. It allows developers to build complex, dynamic, and high-performance web applications with ease. Here are some key concepts of ReactJS:
• Components: ReactJS is built around the concept of components, which are small, reusable pieces of code that encapsulate the functionality and state of a part of a web application. Components can be combined to create complex user interfaces.
• Virtual DOM: ReactJS uses a virtual DOM, which is a lightweight copy of the actual DOM that is used for efficient updates of the user interface. Changes made to the virtual DOM are compared to the actual DOM, and only the necessary changes are made to update the UI.
• JSX: JSX is a syntax extension of JavaScript that allows developers to write HTML-like code within their JavaScript code. JSX makes it easier to write and manage complex UI components.
