The React framework makes building interactive UI components a breeze. Its component logic is written in JavaScript, making it easy to register event handlers for UI elements. In addition, React components implement a render method to return a JSX representation of the UI component. The JSX code is then translated into browser-compatible HTML.
This feature improves performance by avoiding reloading the entire page. React uses a virtual DOM to save time by refreshing only the sections that need changing. This allows websites to run faster. In addition, it also helps to improve SEO by not having to re-render the entire page.
Components in React are reused in different parts of an application. Each component must implement a render method to specify how it will render to the DOM. It can also receive props, which are properties passed to it by its parent component. This way, it is easier to debug errors and pinpoint their location.
Using React makes it easy to reuse assets. For example, it saves designers time because they don’t have to draw the same corporate logos over. Additionally, it makes testing easy. While traditional UI browser testing requires the use of multiple browsers, React components can be tested directly in the node command line.
