What are the best practices for using loops in JavaScript?

When using loops in JavaScript, consider using 'forEach' for arrays, and avoid modifying the array while iterating.

Why should I avoid modifying the array while iterating?

Modifying the array can lead to unexpected behavior, such as skipping elements or infinite loops.

Are there performance differences between 'for' and 'forEach'?

Yes, traditional 'for' loops can be faster in some cases, especially with large datasets, but 'forEach' is more readable.

What about using 'map' instead of 'forEach'?

Use 'map' when you need to transform data and create a new array, while 'forEach' is for executing a function on each element.
