What are JavaScript timers and how do they work?

JavaScript timers are functions that allow you to execute code after a specified delay. They include setTimeout and setInterval.

Can you explain the difference between setTimeout and setInterval?

Sure! setTimeout executes a function once after a specified delay, while setInterval repeatedly executes a function at specified intervals.

How do I clear a timer that I set?

You can clear a timer using clearTimeout for setTimeout and clearInterval for setInterval, passing the timer ID as an argument.

Are there any common pitfalls when using timers?

Yes, common pitfalls include not clearing timers when they're no longer needed, which can lead to memory leaks, and using timers in loops without proper control.
