Is React.js A Library Or A Framework?

React.js is a JavaScript library for building user interfaces. It is often referred to as a library rather than a framework. The main reason for this is that React.js focuses on providing the view layer of an application, whereas frameworks like Angular or Vue provide a more comprehensive structure for building web applications.

While React.js can be used to build entire applications, it is not a full-fledged framework like Angular or Vue. React.js is more focused on providing a flexible and efficient way to build user interfaces, rather than dictating the overall structure of an application.

Overall, React.js is best described as a library for building user interfaces, rather than a full-blown framework. It is a valuable tool for creating interactive and dynamic UIs, but it is not a complete solution for building complex web applications from start to finish.
