In JavaScript, one interview question that often pops up aims to test your understanding of asynchronous behavior and the event loop. Consider the following code snippet: At first glance, you might expect the output to be “a”, “b”, “c”, “d”, “e”, because “c” is set to log after 0 milliseconds. However, when you run this code, the output is actually: abdec Why does this happen? Let’s unravel the mystery behind this sequence by delving into the core mechanics of JavaScript’s event loop. Synchronous vs. Asynchronous: The Key Difference JavaScript operates on a single-threaded model, which means it can only execute…
