Strong Community
It's been over 8 years since the initial release of React JS, but Mark Zuckerberg's engineering teams still support it. The fact that it is a technology based on the popular JavaScript language causes the learning curve of React JS to go up very quickly. It means as much that React community is constantly growing and already has nearly 140k stars on Github. Having this in mind, we can say that there will never be an insoluble challenge in your project because the internet is full of React JS-related materials uploaded daily. So even if there will be some game-changing update coming, we'll know that in a matter of minutes.
Stable code
React uses a view-model system as the majority of JS technologies does. The significant advantage of React over the competition is the fact that when we change child elements, parent data does not change. It is due to the one-direction downward data flow used in React. Due to this fact, when modifying an object, the developer only needs to make changes and corrections to it, and only this one element will be updated. It improves the stability of the code and the application's performance.
Easy transition to mobile app
Did you know that you can create React app for the web and easily convert it into a mobile app? It is because React code is highly compatible with React Native code. Therefore, if you anticipate your company's growth and there is a chance, someday you will need a mobile app React JS is a way to go! Transitioning from React JS to RN is a much cheaper and faster option than starting an application in a different language from scratch.
Great performance
The performance of web applications built with React is one of its most substantial benefits. React owes this to the virtual DOM. The classic DOM has a tree structure, so changing something at the top can negatively affect the interface. Virtual DOM, on the other hand, is Facebook's answer to this problem. It allows virtual changes to the DOM. It means that before they are introduced into the actual document object model of the application, and before the user sees the changes, the algorithm checks on vDOM where these changes need to be made and how to do it best. Only then are the changes made to the application's DOM. Its guarantees a much better performance and user experience in dynamic web applications with many interactive elements.
Saved Time & Money
Thanks to the fast and relatively cheap development process, applications developed in React Native are an excellent solution for creating, for example, a Minimum Viable Product. What's more, the nature of this framework allows for quick changes in the project, and any mobile app developed in it is highly scalable.
Great User Interface
App appearance is one of the most critical issues if you want to keep the user with you and make him loyal to your app. User interface is responsible for the visual layer of digital products, and React was created to build them. React components not only save resources but are also responsible for making the app UI. Creating a layer that is visible to the user is like arranging a puzzle because the interface consists of many components connected. Developers can use not only rich libraries of previously prepared components but also create their own using JSX. This flexibility allows for the production of beautiful user interfaces in a relatively short time.
