How Does setTimeout Work? Inside the Browser Event Loop Explained

setTimeout schedules code to run after a delay by handing the callback to the browser’s Web APIs, which later places it in the task queue; once the call stack is empty, the event loop processes the queued callback, illustrating the asynchronous execution flow in JavaScript.
