- This causes the code to look like a pyramid and makes it unable to read To overcome this situation we use promises.
- Working in such environments requires adaptability, teamwork, and continuous improvement.
- Node.js comes with runtime environment on which a Javascript based script can be interpreted and executed (It is analogus to JVM to JAVA byte code).
- In Node.js, first-class functions are used extensively in asynchronous programming to write non-blocking code.
- With this foundational understanding, you can extend the server’s behavior in numerous ways, such as by serving dynamic content or handling different HTTP methods like POST and PUT.
Database and Storage-Specific Web Developer Interview Questions with Answers
Learn how to highlight your skills, experience, and projects effectively. Tests the candidate’s knowledge and experience with network application development, as well as their problem-solving skills. Assesses the candidate’s knowledge and experience in ensuring optimal network application performance. When multiple asynchronous functions are chained together then callback hell situation comes up.
How do you implement WebSockets in a Node.js application?
The event loop is a mechanism in Node.js that allows for executing non-blocking I/O operations. Node.js is a runtime environment for executing JavaScript code outside of a web browser, while JavaScript is a programming language that can be executed in both web browsers and Node.js environments. Node.js is a server-side JavaScript runtime environment built on top of the V8 JavaScript engine, the same engine that powers Google Chrome.
What is the pipe() method in NodeJS?
IoC (Inversion of Control), as the name suggests, is a design principle in software engineering. With IoC, different kinds of controls can be inverted in an object-oriented design to attain loose coupling. The term „controls” refers to any other responsibilities a class may have other than its primary responsibility. These include controlling the flow of an application, controlling the creation of objects, or controlling the binding and creation of dependent objects. IoC allows classes to be loosely coupled, making testing and maintenance easier. Today, the software is rapidly created and features are often changed based on customer needs, and then it is deployed into production.
This ensures that new updates are delivered to Programming language implementation end-users quickly and efficiently, reducing the time between ideation and implementation. Continuous integration and continuous deployment (CI/CD) are essential elements of modern software development. They demonstrate your understanding of the importance of creating a seamless, automated flow from development to deployment.

As discussed above, interviewers look for candidates with a blend of technical know-how, problem-solving abilities, and familiarity with frameworks and tools.
Automated tools are used to assert the new code’s correctness before integration. The version control system is also supplemented with other checks like automated code quality tests, syntax style review tools, and more. The ‘require()’ function is used to import modules, while ‘module.exports’ or ‘exports’ is used to expose functionality from a module.
