In modern technical interviews, particularly for front-end and full-stack engineering roles, recruiters look beyond basic syntax to test your fundamental understanding of the language’s runtime behavior. One classic a question that consistently pops up aims to evaluate exactly how well you grasp non-blocking I/O, concurrency, and asynchronous execution. At first glance, the question seems deceptively simple, often leading freshers into a common logic trap by presenting a brief sequence of console.log statements mixed with a timer. According to technical expert Arunangshu Das, interviewers use this specific puzzle not to test your math or coding speed, but to see if you…
