How can I optimize array iteration in JavaScript?

You can optimize array iteration by using methods like forEach, map, or traditional for loops, depending on your needs.

What are the performance differences between these methods?

Generally, traditional for loops are faster for large arrays, while forEach and map are more readable but can be slower.

Are there any specific scenarios where one method is better than the others?

Yes, for example, if you need to break out of a loop early, a traditional for loop is best. For transforming data, map is ideal.

What about using reduce for iteration?

reduce is great for accumulating values or transforming arrays into a single value, but it can be less intuitive for simple iterations.
