Node.js Practice Exam

Node.js is an open-source, cross-platform JavaScript runtime environment that enables developers to execute JavaScript code on the server side. Built on the V8 JavaScript engine, Node.js is designed for building scalable network applications. It uses an event-driven, non-blocking I/O model, making it lightweight and efficient for real-time applications such as chat services, APIs, and data-intensive solutions.
Certification in Node.js validates a developer’s expertise in using the platform for backend development. It demonstrates a thorough understanding of core concepts, including asynchronous programming, event-driven architecture, and integration with databases and APIs. The certification proves the candidate's ability to design, build, and maintain scalable server-side applications using Node.js.
