What are some tips for improving array performance in JavaScript?

To improve array performance in JavaScript, consider using typed arrays, minimizing array resizing, and using methods like map and filter efficiently.

Can you explain how typed arrays work?

Typed arrays are array-like objects that provide a mechanism for reading and writing raw binary data in memory. They are more efficient for numerical data.

What about the impact of array methods like forEach versus for loop?

Using a traditional for loop can be faster than forEach, especially for large arrays, as it avoids the overhead of function calls.

Are there any specific scenarios where I should avoid using arrays?

Yes, for scenarios requiring frequent insertions and deletions, consider using linked lists or other data structures instead of arrays.
