ReactJS is a popular framework that allows you to build user interfaces using reusable components. It uses the JavaScript syntax extension to create dynamic HTML, which is useful for updating specific parts of a webpage. React treats each section of a user interface as a component, with its own state, methods, and functionality. The library makes it easy to develop interactive web applications, such as games and websites. It is especially useful when you want to build responsive and cross-platform applications.
React JS works by using a virtual DOM, which is a data structure made up of plain JavaScript objects. The DOM is never rendered to the user, so developers only have to modify object states. Besides being fast, React follows the downward data flow pattern, which helps in maintaining code stability. The framework also ensures smooth performance of the application. Thousands of companies around the world have already made the switch to React JS.
React is easier to maintain because it separates the user interface into multiple components. It also allows you to reuse the same component multiple times, making it easier to debug. The design of React allows for components to be nested. Each component must have a render method that specifies how it will render to the DOM. It is possible to pass props to a component and specify the values that should be passed to it.
