Node.js is an open-source, cross-platform JavaScript runtime environment that’s well-suited for developing I/O intensive web applications, including video streaming sites and single-page applications. It empowers developers to write web applications in JavaScript and run them on a variety of operating systems, including OS X, Microsoft Windows, and Linux. Node.js offers a library of JavaScript modules, simplifying web application development.
Angular, on the other hand, is a JavaScript framework that employs TypeScript, a compiled, typed superset of JavaScript. Angular focuses on building user interfaces for web and mobile applications. It serves as an application-design framework and development platform, enabling the creation of efficient and sophisticated single-page apps.
