What are the best practices for using setInterval in JavaScript?

When using setInterval, it's important to ensure that you clear the interval when it's no longer needed to prevent memory leaks. Also, consider using setTimeout for better control over execution timing.

Can you explain why clearing the interval is important?

Clearing the interval is crucial because if you don't, the function will continue to execute even if it's no longer needed, which can lead to performance issues and memory leaks.

Are there any alternatives to setInterval?

Yes, alternatives include using setTimeout recursively, which can provide more precise control over timing and execution.

What about using requestAnimationFrame instead?

requestAnimationFrame is a great alternative for animations as it syncs with the browser's refresh rate, providing smoother visuals and better performance.
