React is a powerful JavaScript library developed by Facebook for creating user interfaces specifically for single-page applications. The component-based architecture allows developers to create reusable UI components. This makes the development process efficient and maintainable. A typical React application is structured in directories and files. There are different file extensions used in React development, each with a particular purpose. For instance .js or .jsx files are for JavaScript and JSX code, respectively. On the other hand, .css files are for formatting elements. Knowing these file extensions is crucial for several reasons: improves code readability; helps fix bugs and ensures ... Read More

React is a well-known JavaScript library mostly used to build dynamic and interactive user interface applications for the web. It is a creation of Facebook, which lets developers create reusable UI components and also provides a virtual DOM on which rendering is to be done. React Native is a new concept that applies the logic of React to developing mobile applications. That means developers can write mobile apps for both iOS and Android operating systems. Using React Native, one would get identical compiling with a single codebase. Using native components instead of elements from the web gives a real ... Read More

Virtual DOM and Real DOM are important terms in web development. They both influence the rendering and updating of user interfaces. Virtual DOM is a transparent overlay that maximizes updates, whereas Real DOM is the underlying structure that the browser manipulates. To maintain optimal performance, web development frequently calls for effective ways to handle user interface (UI) modifications. Given their frequent changes and performance issues, traditional Document Object Models (DOMs) have been replaced by Virtual DOMs in contemporary frameworks. It is very important to understand the differences between Virtual DOM and Real DOM and how current frameworks achieve greater ... Read More
