What are some common errors in array iteration?

Some common errors 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 iterate one time too many or too few, often due to incorrect loop boundaries.

How can I avoid modifying the array during iteration?

To avoid this, you can create a copy of the array or use methods like filter or map that return new arrays.

What loop types should I consider for array iteration?

You can use for, forEach, map, or for...of loops, depending on your needs and whether you need to modify the array.
