We'll learn how to get the value of a Node in a Linked List at a given Index.
[00:00] Now, let's define the get method. The get method takes a single argument, index. It'll return us the value of the node at that index if one exists. This will start to look pretty familiar. Once again, we're going to iterate through each of the nodes until we find the one we're looking for. [00:40] Now that we have the current node, we simply return its value. Again, let's go check our tests. Similar story as before, create a new linked list, we insert 3 elements and then we're going to try and get the value of a particular index. [01:02] If we scroll up, we can see we now have 4 passing tests. 2 more to go.
