Sample Practice Test Questions:

  1. Question: What is the primary use of the Node Package Manager (npm) in Node JS?

    • A) To compile Node JS applications

    • B) To manage Node JS project dependencies

    • C) To create new Node JS projects

    • D) To optimize Node JS applications for performance

    • Answer: B) To manage Node JS project dependencies

    • Explanation: npm is an integral part of Node JS, primarily used for managing project dependencies. It allows developers to install, update, and manage libraries and packages that a project requires. This is crucial in modern development, where leveraging existing packages for functionality is a common practice, reducing development time and increasing efficiency.

  2. Question: In Node JS, how are ‘Buffers’ primarily used?

    • A) For handling file paths

    • B) For handling streaming data

    • C) For storing user session data

    • D) For managing environment variables

    • Answer: B) For handling streaming data

    • Explanation: Buffers are used in Node JS to handle binary data while performing operations like reading from or writing to files, interacting with streams, or handling TCP streams. In scenarios where dealing with large volumes of data is common, buffers play a vital role in efficiently handling this data in chunks, ensuring better performance and resource management.

  3. Question: Which feature of Node JS aids in executing non-blocking operations?

    • A) Event Loop

    • B) Callback Queue

    • C) Child Processes

    • D) Global Scope

    • Answer: A) Event Loop

    • Explanation: The Event Loop is a fundamental aspect of Node JS that allows non-blocking operations. It handles asynchronous callbacks and is a pivotal part of the Node JS runtime environment. The Event Loop works by polling for events and executing the callbacks associated with these events, thus facilitating a non-blocking, event-driven architecture that is central to Node JS’s performance efficiency.

  4. Question: What does Express.js primarily provide for Node JS applications?

    • A) Database integration

    • B) A robust plugin system

    • C) A server-side web application framework

    • D) Enhanced security features

    • Answer: C) A server-side web application framework

    • Explanation: Express.js is a popular server-side web application framework for Node JS. It simplifies the development of web applications and APIs by providing a range of features like simplified routing, middleware support, and template engine integration. This makes developing complex applications and services more manageable, allowing developers to focus on application logic rather than the intricacies of underlying HTTP protocols and processes.

  5. Question: In Node JS, what is the primary purpose of using middleware in Express.js?

    • A) To enable real-time communication

    • B) To handle HTTP requests and responses

    • C) To connect to various databases

    • D) To encrypt sensitive data

    • Answer: B) To handle HTTP requests and responses

    • Explanation: Middleware functions in Express.js are fundamentally used to process HTTP requests and responses. They can modify request and response objects, end the request-response cycle, and call the next middleware in the stack. This is crucial for tasks like parsing request bodies, adding response headers, authenticating requests, and logging request details. Middleware provides a flexible way to perform these operations, allowing developers to create modular and reusable code.
