incompl / ctor_name_inheritance.js

Created October 17, 2011 14:34

.name property, constructors, inheritance

	// A weird bug when you inherit from a constructor. You shouldn't
	// inherit from a constructor but when I accidentally did I noticed
	// this weirdness.

	function Foo() {}

	// this should be Object.prototype, or {}, or omitted completely,
	// but certainly not the Object constructor. Still, what follows
	// isn't exactly what you'd expect...
	Foo.prototype = Object;

incompl / __proto__ dne constructor.prototype.js

Created October 20, 2011 02:46

Shows that .__proto__ is not the same as .constructor.prototype

	function Parent() {}
	var parent = new Parent();
	function Child() {}
	Child.prototype = parent;
	var child = new Child();

	// child inherits directly from parent. this makes sense.
	console.log(child.__proto__ === parent); // true
	console.log(child.__proto__ === Parent.prototype); // false

Created May 11, 2012 14:44

Example of box2dweb with C++ heritage noted in comments

	// Code from http://lib.ivank.net/?p=demos&d=box2D

	// These look like imports, but in JavaScript they are just busy-work.
	var
	b2Vec2 = Box2D.Common.Math.b2Vec2,
	b2BodyDef = Box2D.Dynamics.b2BodyDef,
	b2Body = Box2D.Dynamics.b2Body,
	b2FixtureDef = Box2D.Dynamics.b2FixtureDef,
	b2World = Box2D.Dynamics.b2World,
	b2PolygonShape = Box2D.Collision.Shapes.b2PolygonShape;
