JavaScript is a popular programming language that powers most websites, but one concept remains tricky - the event loop. This single-threaded language uses an event loop to handle asynchronous tasks like data fetching and timers. Web APIs provide extra tools for handling network requests, setting timers, and accessing user location.

The task queue holds callback functions from Web APIs, event listeners, and deferred actions. The call stack is where JavaScript keeps track of function calls, processing them in order. The event loop acts as a traffic officer, moving tasks between queues to keep everything running smoothly.

Understanding the event loop is key to writing efficient and asynchronous code in JavaScript.
