How React JS is Rewriting App Development?
Published: 2020-04-15 12:09:14

React JS or React Javascript was launched in 2013 and since then, it has been a bestseller and one of the most favored frameworks of developers. The framework is maintained by Facebook and the developer community together and it has been used as a framework for more than 32,000 websites. In addition, the world’s leading brands such as Apple, Paypal, and Netflix are already using React JS app development. It is one of the oldest Java Scripts that is still in use and is reestablishing new standards of app development.

**How React JavaScript App Development is Changing the IT Landscape:**

React JS becomes a must for single-page applications that are required to be fast, responsive, and error-free. The framework can be considered ‘One Size Fits All’ as the developers can use it to develop a wide base of applications and still it works just fine. The versatility of React JS can be understood by taking a look at the companies that use it. It is just as useful for Fortune 500 companies as it is for startups. Here is a look at how React JS is rewriting [mobile app development](https://enterprise.affle.com/mobile-app-development
).

**Reusability for Enhanced Productivity and Easy Maintenance** 
Applications follow complex logic, and changing algorithms for one portion may affect the other. This usually creates a fussy situation while creating and launching updates. React JS has the ability to reuse system components which is a boon for developers and designers.

Reuse of assets i.e. digital components is a common phenomenon and they usually reemploy digital objects such as checkboxes, buttons. React JS allows developers to reuse a vast majority of digital components that range from highly specific components to root components. This is less time-consuming and ultimately promotes productivity.

A good example would be Walmart which has numerous branches, subsidiaries and sister concerns that have their own online presence. However, their core processes such as image carousel and payment systems are the same. Here, reusability eases up the overall developing process as the developers can use the same components over and over to attain reliability in the process that will also ease-up the maintenance.

**A Virtual Document Object Model (DOM)** 
Developers clearly understand how a heavy application that also has a high-load will impact the app structure. DOM has a tree-like structure and it is complexly connected to the multiple layers of the application. Even small changes in the upper layer can affect the whole interface and high-end app engines cannot ensure that such a phenomenon would not exist.

However, React JS app development excels in this situation as well. It has a virtual DOM that allows the developers to make virtual changes and test them. Once they have tweaked the changes with the help of diff algorithm they can implement the changes in the actual DOM tree.

React JS is a must-go framework for heavy apps that require faster loading. This feature of React JS ensures that the process does not become time-consuming and the changes are done without any errors.

**React JS App Development is SEO-Friendly** 
 Common or local search engines often fail to read apps that have heavy JavaScript. This does not mean that the developers should not create heavy JavaScript apps. In such situations, developers prefer to React JS as it can run on the server and it can render and return the virtual DOM to the browser as a standard webpage.

Although large enterprises such as Google have improved their algorithms to rectify this scenario, less popular browsers such as Bing, Yahoo, etc. are still unable to detect JavaScript-heavy apps.

**Developer Toolset** 
Developers that are surrounded 24/7 by work cannot afford to learn new technologies every now and then. It requires careful implementation of new tools and techniques along with a hefty amount of time to create a sustainable learning environment.

However, not every framework or library comes with an exclusive toolset that suits the needs of a specific project. React JS comes with an exclusive toolset that contains capable design and debugging tools.

In addition, it also includes browser extension for developer tools that work with both Chrome and Firefox. It allows developers to inspect their current state, and compare parent and child components with ease.

**Native Model for React JS App Development** 
Developers call React JS a ‘Learn Once – Write Anywhere’ library due to its functionality. React JS uses the same design patterns and transition process for both web and native app development. This works for mobile app development as well. Developers can combine React with plain JavaScript and develop native apps with rich UI for both Android and iOS.

Some other features that aid developers in native app development are real-time reload, ability to reuse components, modular architecture, portability, generous ecosystem and open-source. Social media giants such as Instagram and Facebook were innovators and early adopters of React JS including other prestigious brands such as Skype, Airbnb, and Tesla.

React JS is one of the best frameworks for developing both small and large-scale applications that require dynamic data. In addition, the developers are also blessed with perks that allow them to create an interactive and smooth UI/UX. All these factors make it a must-have for both small and large-scale organizations.
