Building a complex, high-load app makes it mandatory for a business to define the structure of the app at the start since it can impact the overall performance of the app.

To put it simply, the DOM (Document Object Model) is tree-structured, which makes it difficult to make even minor modifications at a higher level layer as that can significantly impact the user interface of your application.

To address this issue, a virtual DOM feature has been introduced by Facebook. Virtual DOM is nothing but a virtual representation of DOM that allows developers to test all changes to the virtual DOM in the beginning, to calculate risks with each modification.

This helps you to maintain high app performance and also guarantees a better and more satisfying user experience. Further, owing to its modular structure, the React JS code is easy to maintain and update. It can be used for both client and server-side, helping you save a significant amount of time and money.

The quality of the user interface in any web application cannot be over-emphasized. A poorly designed user interface is not only frustrating to manage, but it also lowers the chances of application success.

React JS allows you to build high-quality and rich user interfaces through its declarative components and enhances the chances of building applications with high-quality UI that is loved by the users.

React JSX is a syntax extension to JavaScript (optional) that makes it easier to write your own components by accepting HTML quoting and making subcomponent rendering easier.

Further, it can prove useful in building custom components or high-volume apps, making it much simpler to convert from HTML mockups to ReactElement trees. The library also provides React developers with error messages and informative warnings, along with helping them prevent code injections.

React JS is backed by solid support of independent contributors and the credibility of Facebook, which makes it completely safe for your applications.

Currently, the React GitHub repository numbers over 1100 independent contributors where users can ask their questions on Stack Overflow, Freenode IRC, Discussion forum, social media platforms, and many others.

Another business-related benefit with React JS is that it allows for a good abstraction layer. What this essentially means is that the end-user can't access the complex internals.

Your developer only needs to know the basics and not many of the internal functionalities.

Further, React JS does not dictate any fixed architectural patterns such as MVP, MVC, and MVVM. On the contrary, you enjoy the complete freedom to design your app's architecture the way you like.

One of the main challenges that startup owners face with their single-page applications is SEO compatibility. Moz (a leading platform to check web domain authority) suggests that the lower the page load time and faster the rendering speed, the better the chances of the app ranking high on Google.

React JS, because of its fast rendering as compared to other frameworks, reduces the page load time significantly, which helps businesses to rank higher on the Google search engine results. Known to be a completely SEO friendly front-end library, React JS also offers you the advantage of more website visibility.

The opportunity to learn any new technology and implement it in the real project sounds like an exciting prospect, but that makes sense only if you can actually apply it in the development environment. This requires the library or stack you are using to have the proper toolset for optimally efficient performance.

React JS offers this advantage as it comes with all the debugging and design tools. React JS developer toolset is primarily a browser extension that is available for both Firefox and Chrome. It allows front end developers to observe various reactive component hierarchies and discover all the components.

React JS is known to follow downward data flow, which makes sure that the parent structure doesn't get affected by any alterations or modifications to its child structure.

The result of this is reflected at the time of developers making changes in an object, as they only need to modify its states and make proper amendments to update only a specific component.

This kind of data flow and structure ensures better code stability and smooth performance of the applications.

Trusted by some of the renowned names worldwide, including Facebook, Netflix, Instagram, Dropbox, PayPal, and many more, React JS as a front end library is undoubtedly a high-quality tool for app development.

Thousands of organizations, including some of the Fortune 500 companies, are using React JS for both their websites and mobile apps.

While Tesla, Airbnb, Tencent, and Walmart are some of the top brands that built their mobile apps using the React Native framework, the React web framework is being utilized by top companies, including Paypal, BBC, Lyft, The New York Times, and Netflix.
