Application

IWM Browser Applications follow a common three phase pattern, shared by many programming environments as diverse as Processing, Arduino, Intern, etc.

• Instantiate: Initialize the application, in this case a singleton and it's instance variables
• Setup: Build more complex parts of the application, by loading data, creating the UI...
• Run: Enter and run the main loop of the application.

class IApp extends Interface {
    setup() { return this }
    run() { return this }
}

In practice the pattern may be more complex, because the setup phase can only be entered after loading things, a main loop cannot be entered because requirements are not met, etc. But the basic structure is always the same:

The setup and run methods can also be chained:
