Please don't just quote Crockford as gospel truth. Crockford's prototypal revelation is only a slight alteration of the standard constructor pattern, and not a particularly useful one. You still have a class (the object that serves as a prototype for every instance you create), it doesn't add any particular flexibility, and it's quite slow. I encourage you to run the tests yourself: http://jsperf.com/object-create-vs-crockford-vs-jorge-vs-constructor/9 http://jsperf.com/object-create-vs-crockford-vs-jorge-vs-con... For me, that test clocks using Crockford's pattern to instantiate objects as 80% slower in Safari and Firefox, and 95% slower in Chrome, when compared to a standard use of JS prototypes.
