What is the memory usage of different JavaScript iterables?

Can you explain the memory usage of different JavaScript iterables?

Sure! In JavaScript, iterables like arrays, sets, and maps have different memory footprints. Arrays are generally more memory-efficient for storing ordered data, while sets and maps can consume more memory due to their key-value storage.

How does the memory usage compare between arrays and sets?

Arrays typically use less memory than sets because they store elements in a contiguous block. Sets, on the other hand, require additional memory for maintaining uniqueness and internal structures.

Are there any performance implications of using one over the other?

Yes, using arrays can be faster for indexed access and iteration, while sets are better for operations that require uniqueness and frequent additions or deletions.

What about memory usage in large datasets?

For large datasets, it's crucial to consider the type of iterable you use. Arrays may lead to higher memory consumption if they grow too large, while sets can help manage unique values but at a higher memory cost.
