What are some common mistakes when iterating over arrays?

Some common mistakes include off-by-one errors, modifying the array while iterating, and using the wrong loop type.

Can you explain the off-by-one error?

Sure! An off-by-one error occurs when you incorrectly set the loop's starting or ending condition, often leading to skipping the first or last element.

What about modifying the array during iteration?

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

What loop types should I use for different scenarios?

For simple iterations, a for loop is great. For array methods like forEach, use them when you don't need to break out of the loop.
