Understanding The React.js Library And Its Key Features
Virtual DOM
React.js uses a virtual DOM, which is a lightweight representation of the actual DOM. By using a virtual DOM, React.js can efficiently update only the parts of the UI that need to be changed, without having to update the entire page.
React.js uses a syntax called JSX, which allows developers to write HTML-like code within their JavaScript code. JSX makes it easier to write and understand React.js components.
React.js components are reusable pieces of code that can be composed to create complex UIs. This component-based architecture makes it easier to maintain and update large applications.
React.js uses a unidirectional data flow, where data flows from parent components to child components. This makes it easier to understand and debug code, as well as reduce the likelihood of bugs and errors.
React.js can also be used to build native mobile applications using a framework called React Native. React Native allows developers to use the same components and codebase for both web and mobile applications.
