# Benefits of ReactJS

I started learning Reactjs in January this year. My learning experience has been quite of ups and downs but what I learn in the past few months is that Reactjs is one of the best libraries available.

I discovered various advantages of using the ReactJS framework. Few are listed below-

**Quick Learning Curve
**

React is an extremely straightforward and compact library that solely addresses the view layer. After only a few days of lesson reading, any Javascript developer can learn the fundamentals and begin creating an outstanding web application.

According to the React tutorial, "Thinking in React" could differ slightly from how you are used to thinking because it takes a new approach, but as you use it more, it will become lot simpler and more natural.

**Use of Reusable Parts
**

React offers a component-based structure. A higher level wrapper component is then written. It continues in this manner until you have your app as the sole root component.

Each element chooses how to be rendered. Every element has a unique internal logic. The outcomes of this strategy are astounding. Anywhere you need them, components can be reused. As a result, your program has a uniform look and feel, it is simpler to maintain and expand your codebase thanks to code reuse, and it was also made easier to develop.

**Quick rendering with a virtual DOM**


You must take into account potential performance concerns when developing a web application that requires a lot of UI and display modifications. DOM manipulations are still not that quick, even if modern javascript engines are quick enough to handle such complicated applications. When it comes to website performance, updating DOM is typically the bottleneck. 


**Innocent Abstraction**


React's ability to create a good abstraction, which implies that it doesn't expose any complicated internals to the user, is one of its strong points.

For the sake of a clear abstraction, those kinds of details ought to be retained as internals. To master React, you only need to be familiar with the life cycles, states, and properties of each component. Since React is simply about the view layer and does not impose any patterns or architecture like MVC/MVVM, you are free to design your app's architecture any way you see fit.


**Flux and Redux**


Facebook has created and still maintains the architecture ofFlux, which they use for their web apps. By allowing for unidirectional data flow, it enhances React components. The general organization is as follows.

To update stores, we can design activities that are coordinated by a central dispatcher. Following that, the views are revised to reflect the changes in those stores. To avoid having to constantly strive to maintain your model data in sync throughout the application, MVC structures all the data that will be presented by components in stores rather than duplicating it as models.

Flux is not a ready-to-use library, but there are implementations that are. The most well-liked one is Redux, which is a reworking of the flux architecture. It offers a single store that is not necessary during flux. In my opinion, you should make this choice in order to have a single source of truth. Where you store all the application data is in a single object. This makes it simpler to watch and control. Any modification to the store (data) will cause relevant components to render, and the view is constantly maintained up to date with the data.

**Outstanding Developer Tools**


Another significant consideration when selecting a development platform is the developer toolset. You should be aware of two excellent tools: Redux developer tools and React developer tools. Both are available as extensions for Chrome.

The best way to explore react components within their hierarchy and to see their current props and states is with React Developer Tools. A screenshot is provided below. Here, we are looking at elements of Jotform 4.0. The hierarchy position and props of the selected component are shown in the rightmost pane, while its left side is highlighted.

You should absolutely check Redux Developer Tools for Chrome if you use the Redux library. You can keep an eye on dispatched actions, existing store conditions, and store updates. Additionally, you can send out activities or make shop modifications, and your view will immediately reflect the changes. Time travel is also a possibility because all the changes are included within the extension. For the sake of debugging, you can capture any state of your application and go back to it.

**React Native**


Learn React Native React Native is an added benefit of React. As its designers claim, React is a "learn once, write anywhere" framework rather than a "write once, run anywhere" library. Yes, you can use React Native to create native apps for iOS and Android. You can use the same methodology and architecture even though you can't utilize the exact same code you produced for the web.
