Data structures

A data structure is a particular way storing and organizing data in a computer for efficient access and modification. Data structures are designed for a specific purpose. Examples include arrays, linked lists, and classes.

https://github.com/candytale55/nodes_js_datastructs

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."
