// Type Pattern

<package>.T = (function () {
	var T = {};

	// Shared properties and methods go here

	T.create = function (…) {
		vart = Object.create(this);
		// Assign the own properties here
		return t; 
	}
	return T;
}());

// Instantiate with: varx = <package>.T.create(…);
// The "type" object and the prototype are one! 
// Differs from operator new, which equates the type with the constructor (prototype separate)
