A JavaScript class to create a basic node that contains data and one link to another node. The node’s data will be specified when creating the node and immutable. A node’s link to the next node is null when there are no nodes to traverse. Plus an example "An ice cream shop that sells three flavors: strawberry, vanilla, and coconut. The signature sundae is made of these three flavors, but new hires have a hard time remembering the order."
