In this video, we will start covering object oriented programming in Javascript. There are several ways to do it - the first is called "classical inheritance".

Here's the link to the "inherit" function I use here:
github.com/nodejs/node-v0.x-archive/blob/master/lib/util.js#L634-L644

Using a constructor, a prototoype, and the "new" keyword, we can create multiple copies or "instances" of a module, each with unique properties, but shared functionality.

We can also implement inheritance in Javascript. If we create a new module, we can inherit the functionality of a parent module with a simple inheritance helper function.
