it's called JavaScript :D
jokes a part, every function is a constructor as well so new function is
always valid.
If the function returns an object, it does not matter which "new" is because
it will be an instance of returned object one.
if it is a primitive it will simply be lost:
var a = new function(){return 123;};
// a is an instance of anonymous function
this allows us to create Python like initializations:
function PythonLike(){
return this instanceof arguments.callee ? this : new arguments.callee;
};
alert(PythonLike() instanceof PythonLike);
alert(new PythonLike() instanceof PythonLike);
true in both cases
jQuery returns a new jQuery.prototype.init where init method shares the same
prototype ... better now? :-)
