React became very popular because of its rapid DOM rendering speed. Though it creates a tree for all nodes, reading and writing the DOM is slow. React JS uses the concept of a virtual DOM that will make it easier. Its popularity can be measured by the fact that even foremost apps like Facebook, WhatsApp, Instagram, and Netflix are making use of the React JS. So, what leads to React JS as a favored technology to develop excellent web and mobile apps? We list down 7 top explanations in support of it.
1. Easy To Learn And Master
2. Reusable Components
React gives a component based structure. It means your lego pieces, indicating those tiny components like button, checkbox, dropdown etc. You develop wrapper components composed of those smaller components. It goes on until you have this one root component and that component is your app.
Each component has its own core logic and decides how it should be rendered. The approach has some astounding result. These are (1) Your app has a consistent feel and look, (2) it is easier to develop your app, and (3) code reuse makes it a lot easier to maintain and grow your codebase.

4. Clean Abstraction
The influential side of React is that it gives a good abstraction. It means that it does not expose any complex internals to the user. If we compare this to Angular: Why should you have to understand an internal process like digest cycles? These details can be kept as internals to give clean abstraction. What you have to learn is a component’s life cycle, pros, and states to master React. React does not command any architecture or pattern like MVC/MVVM. It's only about the view layer and you are all free to design your app’s architecture in any way you see fit. Onearchitecture that fits really well called Flux.
5. Flux and Redux
Facebook introduced and supported Flux architecture and they use it for their web applications. It praises React components by providing unidirectional data flow. The chief idea is to create actions that are arranged by a central dispatcher to update stores. Respect to the changes in that store, the view is updated. Data are to be displayed by components that are kept in stores. They are not duplicated as models in MVC structure. It saves you from trying to keep your model data in sync during the application all the time.
Regrettably, flux is not a ready to use library though there is such execution. The popular one is Redux, a kind of reinterpretation of Flux architecture. It provides a single store and this is a great decision you should make for having a single source of truth.

7. Great Developer Tools
React JS was developed keeping the requirements of software developers in mind. That is the reason React JS comes with a tool set that earns accolades from the developers. React Developer Tools has been designed as a Chrome dev extension that allows you to perceive reactive component hierarchies and observe a component’s present state and props. There are two great tools you should be aware of Redux Developer Tools and React Developer Tools. Both can be installed as Chrome extensions.
If you are a developer who is worried about single page applications and desire to come up with fast, responsive and user-friendly apps, React JS is certainly a worthy choice. If you want to develop large-scale apps with frequently changing data, React JS can support you to meet the challenge in a successful manner.
