How can I improve the performance of array iteration in JavaScript?

You can improve performance by using methods like forEach, map, or traditional for loops. Each has its pros and cons.

What are the differences in performance 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 large datasets or performance-critical applications, stick to traditional loops. For smaller arrays, use forEach or map for cleaner code.

What about using reduce for iteration?

reduce is great for transforming arrays into single values, but it can be less performant for simple iterations compared to for loops.
