Why react became so popular?

React has become increasingly popular for enterprise development in recent years for several reasons:

Virtual DOM: React uses a virtual DOM (Document Object Model) to improve performance by limiting the number of changes made to the actual DOM. This can be especially beneficial for large, complex web applications where performance is critical.
Components-based architecture: React uses a component-based architecture, which allows developers to build reusable, modular code that can be easily maintained and updated. This is particularly useful for large enterprise web applications where scalability is important.
Large developer community: React has a large and active developer community, which means that there is a wealth of resources and support available for developers. This includes a wide range of tutorials, sample code, and third-party libraries.
Strong ecosystem: React has a strong ecosystem of supporting tools and libraries such as Redux, Next.js and more. These tools and libraries are built to work seamlessly with React and make development faster, more efficient and reliable.
Cross-platform: React can be used to build web, desktop and mobile applications using React Native. This allows the reuse of code and increase the productivity of the development team.
Popularity: React is a very popular framework among developers and companies. This popularity means that a lot of developers are familiar with it, making it easier to find and hire developers with React experience.
Suitable for large projects: React is suitable for building large and complex web applications that need to handle a large amount of data and maintain high performance.
Server-side rendering: React can be rendered on the server-side which improves the performance of the application and allows developers to build SEO-friendly web apps.

Overall, React's popularity in enterprise development is due to its performance, scalability, reusable components, large developer community, a strong ecosystem, cross-platform capabilities and suitability for large projects. These features make it an ideal choice for building high-performance, maintainable and scalable web applications that are suitable for enterprise environments.
