Timer

A timer is a software or hardware mechanism that triggers an event or executes a function after a specified delay or at regular intervals. In programming, timers are used for scheduling tasks, implementing timeouts, creating animations, and managing asynchronous operations. They are fundamental in event-driven systems, real-time applications, and user interface development.

Also known as: Timeout, Interval, Scheduler, Delay, Clock

Why learn Timer?

Developers should learn about timers to handle time-based operations efficiently, such as debouncing user input, polling APIs, or implementing retry logic in network requests. They are essential for building responsive applications that require delayed actions, periodic updates, or timeout management, commonly used in web development, game programming, and embedded systems.
