The event loop is a fundamental programming construct that enables applications to handle multiple operations concurrently, even when some of those operations might take a significant amount of time to complete. At its core, an event loop continuously waits for and dispatches events or messages in a program. This mechanism is crucial for non-blocking input/output (I/O) operations, allowing a program to remain responsive while waiting for external operations, such as network requests or file system interactions, to finish. Essentially, instead of halting all other activity while one task is pending, the event loop allows the program to switch to other available tasks, picking up the results of the longer operations once they are ready.
