Data Structures Introduction

Data structures are basically just collections of values with relationships among them and functions/methods that can be applied to the data. Arrays and objects are built-in data structures.

For example, arrays store data in a sorted order. They also come with built-in methods like filter or reverse that are inherited from the Array prototype.

In the same vein, we will be creating custom data structures by defining our own classes. Instances of these classes will organize the data in specific ways and will inherit methods and properties that allow us to manipulate the data.
