So you want to write an actor

Starting out with primitive types

So you have an idea for a Firefox developer tool. You (obviously) want it to work on Fennec and Firefox OS, so it needs to use the remote debugging protocol. You have a backend:

function SimpleBackend() { }

SimpleBackend.prototype = {

// Widgets are dumb UI implementations sharing a specific interface, which
// defines how interaction with their contents happen.

// The common interface is defined in the MenuContainer constructor
// documentation, in ViewHelpers.jsm (you really don't need to care about this
// if you're not actually writing a widget; furthermore, a <xul:menulist>
// implements all those methods by default, so it can be considered itself a
// widget).

// This is how it is, because it's redundant to write the same UI interaction

In toolbox.js:
let Telemetry = require("devtools/shared/telemetry");

And in telemetry.js:
this.Telemetry = function Telemetry() {
  this.logOncePerBrowserVersion = this.logOncePerBrowserVersion.bind(this);
  this.logEvent                 = this.logEvent.bind(this);
  this.logId                    = this.logId.bind(this);
  this.log                      = this.log.bind(this);
};
