Example of how to avoid sharing array/object references between kinds in Enyo (or JavaScript).

Example.js

enyo.kind({
  name: "sample.Control",
  // some property that is an array that gets modified per-instance
  // means we can't supply one to be shared for all instances
  // so we assign it to null
  myArrayProp: null,
  constructor: function () {
    // here we can use 'this' for our instance and assign a new array
    // that will not be shared with other instances of our kind
    this.myArrayProp = [];
    return this.inherited(arguments);
  }
})
