ReactJS is favored for its ease of learning, user-friendly code, and flexibility. Additionally, it is designed to be modular, allowing developers to create components that can be reused throughout the codebase. Moreover, it utilizes a virtual DOM (Document Object Model) to render the UI, which is faster and more efficient than other frameworks.
Many large companies, such as Facebook, Netflix, Instagram, Dropbox, AirBnB, and Yahoo, have adopted ReactJS for their applications. The potential benefits of using ReactJS include scalability, high performance, and access to a large and active developer community. All of these features make ReactJS a great choice for companies looking to create dynamic and interactive UIs that can handle large amounts of data.
