Edit Question
Title
Body
In JavaScript what is the difference between these two examples: Prerequisite: function SomeBaseClass(){ } SomeBaseClass.prototype = { doThis : function(){ }, doThat : function(){ } } Inheritance example A using Object.create: function MyClass(){ } MyClass.prototype = Object.create(SomeBaseClass.prototype); Inheritance example B using the new keyword function MyClass(){ } MyClass.prototype = new SomeBaseClass(); Both examples seem to do the same thing. When would you chose one over the other? An additional question: Consider code in below link (line 15), where a reference to the the function's own constructor is stored in the prototype. Why is this useful? https://github.com/mrdoob/three.js/blob/master/src/loaders/ImageLoader.js Excerpt (if you don't want to open the link): THREE.ImageLoader.prototype = { constructor: THREE.ImageLoader }
