Event loop is the secret sauce that keeps your JavaScript code running smoothly, like a well-oiled machine in a factory churning out widgets. It's the heart of the JavaScript runtime, constantly pumping life into your code and keeping things moving along, even if that means occasionally getting stuck in an infinite loop and bringing the whole factory to a grinding halt.
