What are common mistakes when using setInterval in JavaScript?

What are common mistakes when using setInterval in JavaScript?

Some common mistakes include not clearing the interval, using setInterval instead of setTimeout for one-time tasks, and not accounting for the delay in execution.

Can you explain why not clearing the interval is a mistake?

Not clearing the interval can lead to memory leaks and unexpected behavior, as the function continues to execute even when it's no longer needed.

What happens if I use setInterval for a task that only needs to run once?

Using setInterval for a one-time task can cause it to run multiple times, leading to performance issues and unintended side effects.

How can I properly clear an interval?

You can clear an interval by using the clearInterval function and passing the interval ID returned by setInterval.
