ReactJS, commonly referred to as React, is an open-source JavaScript library for building user interfaces. It allows developers to create reusable and interactive UI components that update efficiently and automatically in response to changes in data, providing a smooth and dynamic user experience in web applications. React follows a declarative approach, where developers describe how the UI should look based on the application's current state, and it handles efficiently updating the DOM to reflect those changes.
