This test covers essential skills needed for advanced-level Node.js development. It begins with evaluating candidates’ understanding of Node.js features, such as its asynchronous event-driven architecture, non-blocking I/O model, and the use of the V8 JavaScript engine. These features are crucial for building high-performance and scalable applications.

In the context of software engineering, the test assesses knowledge of advanced principles, including writing efficient server-side scripts, managing application state, and integrating with various frameworks like Express.js. These skills are vital for developing robust and maintainable server-side applications.

For web development, the test evaluates candidates’ ability to implement RESTful services, handle real-time communication using WebSockets, and manage data streams efficiently. Additionally, the test covers security best practices, ensuring candidates are aware of common vulnerabilities and how to mitigate them to protect applications from potential threats.
