+* unlike an array, a list does not provide constant time access to an index (as it needs to interact through all k elements), however addition and removal of elements are constant time.
+* to remove a node you set `prev.next` equal to `node.next`. if it's a double list, you also update `node.next` with `node.next.prev` to `node.prev` (and deallocate the memory).
