What are the performance implications of array iteration in JavaScript?

Array iteration in JavaScript can vary in performance based on the method used, such as for loops, forEach, or map.

Which method is the fastest for iterating over large arrays?

Typically, traditional for loops are faster than forEach and map, especially for large datasets.

Are there any trade-offs with using for loops?

Yes, while for loops are fast, they can be less readable and more error-prone compared to higher-order functions.

What about using modern features like for...of?

The for...of loop is more readable and works well with iterable objects, but it may be slightly slower than traditional for loops.
