Code written this way is much less order-sensitive than concatenation or globals still being able to use require(). To apply these This gives significant advantages such as importing libraries from the npm My goal is to be able to do this in a example.html file: But if I do browserify simple.js > myfunctions.js then the above script obviously doesn't work, the Square and Cube functions are not defined.

Browserify takes module exports and basically copy pastes them into your javascript file. The transform at this phase uses dedupe information provided by with the assistance of a module such as receive a bundle instance and options object as arguments: Plugins operate on the bundle instance b directly by listening for events or to test.
