What is the difference between preventDefault and stopPropagation?

Can you explain the difference between preventDefault and stopPropagation in JavaScript?

Sure! preventDefault stops the default action of an event from occurring, while stopPropagation prevents the event from bubbling up to parent elements.

Can you give me an example of when to use each?

Absolutely! Use preventDefault when you want to stop a form submission, and stopPropagation when you want to prevent a click event from triggering on parent elements.

What happens if I use both in the same event?

If you use both, the default action will be prevented, and the event won't bubble up. This can be useful for controlling event flow.

Are there any performance implications of using these methods?

Generally, the performance impact is minimal, but excessive use in complex applications can lead to harder-to-maintain code.
