Today we will discuss one of the most popular open-source JavaScript libraries that are widely used to build user interfaces for web applications. React is a components library that can be easily managed and rendered on the web page. So React is developed by Facebook
React works on Virtual DOM. That is a lightweight copy of a Real DOM. One of the key features of V-DOM is it enables the faster rendering of web pages.
React offers a component-based architecture. This means you can make reusable components that can be re-used anywhere inside your app. This approach speeds up your development. Those components can easily be styled with CSS or other libraries.
Warning: React deprecate the Create-react app. We recommend you to use a framework
Advantages and disadvantages of React
React is a popular JavaScript library that can help you build OnePage web apps in a number of ways. But, like any technology, it has some advantages and disadvantages as well. Here are some of the advantages and disadvantages of React.
Advantages
Reusable components: Components that can be reused: React enables developers to build UI components that are easily managed and rendered on web pages. This makes development quicker and more efficient and ensures that the user interface is consistent throughout the application.
JSX: React uses JSX, which is a syntax extension that allows developers to write HTML-like code within their JavaScript files, making it easier to create and manage complex UI components.
Virtual DOM: React uses a virtual DOM, which means it only updates the parts of the page that have changed, rather than re-rendering the entire page. This results in faster page load times and improved performance.
Disadvantages
No Built-in Routing: React does not provide built-in routing, which means developers need to rely on third-party libraries or create their own solutions.
Complex Configuration: Complex Configuration: Setting up a React project with all the necessary tools and dependencies can be a complex and time-consuming process, especially for beginners who may struggle with the configuration process.
View Layer Only: React focuses solely on the UI layer of an application, which means additional technologies must be used for other aspects of development, such as data management and backend integration.
