The importance of the Module class to NodeJs

Interesting:

The Module type found in module.js has two main roles inside of Node.js. First, it provides a foundation for all Node.js modules to build off of. Each file is given a new instance of this base module on load, which persists even after the file has run. This is why we are able attach properties to module.exports and return them later as needed.

The module’s second big job is to handle Node’s module loading mechanism. The stand-alone require function that we use is actually an abstraction over module.require, which is itself just a simple wrapper around Module._load. This load method handles the actual loading of each file, and is where we’ll begin our journey.
