How do different JavaScript collections compare in performance?

How do different JavaScript collections compare in performance?

JavaScript offers several collection types like Arrays, Sets, and Maps. Each has its own performance characteristics depending on the operation.

Can you explain the performance differences for adding and removing items?

Sure! Arrays have O(1) for adding/removing at the end but O(n) for the beginning. Sets and Maps have O(1) for both operations.

What about searching for items in these collections?

Searching in Arrays is O(n), while Sets and Maps provide O(1) average time complexity for lookups.

Which collection should I use for a large dataset?

For large datasets, consider using Sets or Maps for better performance in adding, removing, and searching items.
