⚠️ In most cases, this should be an O(1) operation. However, there are

Returns an object which is able to sift through the values in this collection.
The order by which the elements are traversed depends on the kind of collection. For unordered collections, the iteration order is unspecified and may even differ between two iterations on the same collection.
Remove all elements from this collection, effectively setting the collection to the empty collection.
Copies all elements in the collection to a new one of the same kind.
Converts the entire collection to a range.
