What this is referring to is a code paradigm called Object Oriented Programming. This uses objects and methods to perform actions in the same way that real-world objects have state and behavior.
For example, the calculator on my desk right now can be switched on and off. In the code you'd represent that behaviour using properties in an object.
The calculator can perform actions like adding numbers, subtracting numbers, multiplying them or divide numbers. You can use methods (which are really just functions) to represent that functionality. Methods represent behaviour. Adding numbers is behavior - performing an action.
Object Oriented Programming can be applied to almost any language.

What it essentially is, is a method of programming. It makes programming structured and modular rather than a mere list of instructions from top to bottom in a script.
Wikipedia here describes OOP as "programming paradigm based on the concept of "objects", which may contain data, in the form of fields, often known as attributes; and code, in the form of procedures, often known as methods. A feature of objects is that an object's procedures can access and often modify the data fields of the object with which they are associated"
The best way of understanding OOP is to practice it.
I don't know how far along you are in your Treehouse journey. But I suggest you try the JavaScript courses. Learn the basics first if you haven't already before you move on to OOP concepts. There's content on OOP JavaScript already. And, in the next couple of months a new course on OOP in JavaScript will be released. So I'm confident with practice you'll start to understand :)
