When should I use forEach vs a regular loop in JavaScript?

Can you explain when to use forEach instead of a regular loop in JavaScript?

Sure! Use forEach when you want to iterate over an array without needing to break out of the loop or return values.

What are the performance differences between forEach and a regular for loop?

Generally, a regular for loop can be faster than forEach, especially for large arrays, because it has less overhead.

Are there any situations where a for loop is preferred over forEach?

Yes, if you need to break out of the loop early or if you need to manipulate the index, a for loop is better.

Can forEach be used with objects as well?

No, forEach is specifically for arrays. For objects, you can use Object.keys() or Object.entries() to iterate.
