To see the source to Class.create().

Anyway, here it is:

var Class = {
create: function() {
return function() {
this.initialize .apply(this, arguments);
}
}
}

Does it simply create a constructor function that requires and will call a
method 'initialize' on the object it creates passing it all arguments?

I'm a javascript novice but it sure looks like this is correct. It
seems like Class.create() is designed to allow end users to create
objects with the usual syntax that then call their own initialize
methods.

My question is why do this instead of simply having each constructor
call its own init method? Since prototype.js looks like it is
beautifully coded, I'm sure there is a good reason...anyone ? (a guess
is that this helps avoid global namespace collisions)

In case you're still looking for documentation for prototype.js, I'm
trying to keep something at:
http://www.sergiopereira.com/articles/prototype.js.html

I hope it can be useful while no official documentation is made
available
