The ReactJS framework implements its abstraction of the DOM, and makes all the event machinery fast and efficient. Creating a UI using ReactJS consists of creating some classes with a few methods, which are called by the engine when the page is created or updated.
This approach means that you do not have to worry about what will happen when the DOM changes anymore. All you have to do is implement some methods, and let React take care of the rest.
Implementing classes for React can be done in JavaScript or JSX. We will discuss about it in the next section.
