Whenever we build any application, we have two parts, the frontend, and the backend. The Frontend is the interface where the users interact and the backend is where all the logic is done. Simply, Frontend is the place that has buttons, forms, clickable materials on which the app respond back and the backend is where we store the data, user credential, etc.
Basically, React is more concerned about building interfaces so that the users can interact with, getting data from the users, and then display the information.
Reasons to Learn ReactJS in 2021
1. Simple Prerequisites required for learning React!!!
2. Ease of use
React doesn’t require big lines of codes to program an application. In react, we say that everything is a component. A user writes small codes called components and combines them to form another component. Simply, any app made with React is a tree of components.
For example, if we are building an Instagram app using ReactJS, we will have many components like a separate component for navigation, another one for the story section, also for news feed, then for profile and all other section of the application. Components are like functions. The world has seen a big jump in the increment of the number of developers switching to ReactJS.
There is no actual DOM element in React. It has a virtual DOM. It keeps a lightweight representation of DOM in the memory. This DOM is cheap to create.
React will compare its elements to the previous ones and figures out what is changed, and then it will update a part of the real DOM to keep it in sync with the virtual DOM. So, we need not worry about DOM in a browser if we use ReactJS. The virtual browser is better than the actual browser in case of user interaction.
