Wrapping Up

As we’ve seen, the subtle differences between arrays and linked lists unlock new ways to make our code faster than ever.

By looking at linked lists, you’ve also learned the concept of nodes. However, the linked list is only the simplest of node-based data structures. In the coming chapters, you’ll learn about node-based structures that are both more complex and more interesting—and that will reveal new worlds about how nodes can yield tremendous power and efficiency.
