An applications of ReactJS is known to be made up of the multiple components among which each component that is present in it is responsible for outputting a small, reusable piece of HTML code. The heart of all the react applications is known as the core of ReactJS. In order to allow complex applications to be built of simple building blocks, these components are generally nested with various other components. In order to fill data in HTML DOM, virtual DOM based mechanism is used by the ReactJS. This mechanism is used as it is known to work fast due to its working that involve the changing of individual DOM elements instead of reloading the complete DOM each time.
In order to create the react app that is known to correspond to various elements, react components are written. These components are organized inside higher level components that defines the application structure.
Hence, in order to withdraw these flaws, a new technology ReactJS framework was invented that has been very successful in removing this drawback. The entire application can be divided into various components by the ReactJS. It is known to still use the same traditional data flow, but the change that has happened is that it is not directly operating on the browser's Document Object Model (DOM) instead it has started operating on a virtual DOM. That simply means that rather than manipulating the document in a browser after the changes to the data, ReactJS resolves the changes on a DOM that is built and run entirely in memory. React determines what changes made to the actual browser's DOM, after the updating of the virtual DOM. The web browser's DOM contains the React virtual DOM that is a mere representation of it.
ReactJs is known to have many important features that are as follows:
There are many advantages of using ReactJS, some of them are as follows:
ReactJS is known to have very few limitations as compared to other of its kind. Here are the limitations that are known to be applied to the ReactJS:
