Using React JS, you can create and manage UI components that are reusable throughout your application. This allows for a more organized and streamlined development process.
React uses an abstract copy of the Real DOM, which updates the DOM only when a component needs to change. This avoids layout trashing and makes it easy to test.
React also uses conventions when it comes to naming props. For instance, the Greeting function uses the JSX name property to display the famous introductory “Hello, world!”.
React also uses a SyntheticEvent wrapper to replace the native Event interface. The wrapper allows for an asynchronous event handling model, which can speed up development time.
React JS also uses a Virtual DOM, which is a copy of the real DOM that updates only when a component needs to change. Compared to the Real DOM, the Virtual DOM is a less expensive method of updating the DOM.
The React JS library has a comparatively small size, at less than 6kb when gzipped. This also means that it can be integrated into existing web pages (more).
Using the React JS library is easy, but developers will have to take the time to learn the system. This may be a daunting task, but there are many tools that can help. You can use code analysis tools to find potential mistakes in your code.
React also offers a useful way to create a “Hello World” application. You can create a single button, which will render the famous introductory “Hello, world!”.
