The Event Loop is a fundamental concept in programming, particularly in environments like JavaScript. It allows a program to perform non-blocking operations by managing asynchronous tasks. The event loop continuously checks a queue of tasks and executes them one at a time, ensuring that the main thread remains responsive to user interactions and other events. When an asynchronous operation, such as a network request or a timer, is initiated, it is sent to the event loop. Once the operation completes, its callback function is added to the task queue. The event loop then processes these callbacks in order, allowing the program to handle multiple tasks efficiently without freezing or slowing down.
