What are some performance tips for JavaScript loops?

To optimize JavaScript loops, consider using 'for' loops instead of 'forEach', minimize DOM access, and cache loop length.

Why is caching the loop length important?

Caching the loop length prevents recalculating it on each iteration, which can improve performance, especially in large arrays.

Are there specific types of loops that are faster?

Yes, traditional 'for' loops are generally faster than 'forEach' and 'map' due to less overhead.

What about using 'while' loops?

'While' loops can be efficient too, especially when the number of iterations is not known beforehand. Just ensure to manage the loop condition carefully.
