Objects are a super powerful data structure we use all the time in JavaScript.

In JavaScript we use objects for everything.

They are one of the fundamental built-in data structures, along with arrays.

While arrays store data in “slots” starting at 0 and going up 1, 2, 3…, objects store data in properties.

We commonly access built-in objects in JavaScript and in the Browser or Server environments, where they are used to provide us functionality and utilities.

And we can pass around objects to functions, retrieve them, etc etc.

Super useful.

In this unit we’ll see how to work efficiently with objects.
