Common Node.js Interview Questions for Beginners
Basic Interview Questions Of Node Js
Basic interview questions in Node.js typically test candidates' understanding of core Node.js concepts, such as event loops, non-blocking I/O, and asynchronous programming. These questions assess a candidate's proficiency in using Node.js for building scalable, efficient server-side applications. They also help interviewers gauge a candidate's knowledge of Node.js ecosystem tools, such as package managers (e.g., npm and yarn) and testing frameworks (e.g., Jest and Mocha). By asking these questions, interviewers can evaluate a candidate's potential to contribute effectively to Node.js-based projects.
