Essential Interview Questions for Node.js and React.js Developers
Nodejs And React Js Interview Questions
Node.js is a server-side JavaScript runtime environment that allows developers to build scalable and efficient web applications. It is highly useful because it enables rapid development, provides a wide range of modules for various functionalities, and allows for easy integration with other technologies. React JS, on the other hand, is a front-end JavaScript library that helps developers create interactive and dynamic web user interfaces. It simplifies UI development, improves code reusability, and enables efficient state management, making it a valuable tool for building modern web applications.
