Object.create

In order to create objects nicely in JavaScript, Crockford suggests:

if (typeof Object.create !== 'function') {
Object.create = function () { // create a method of the universal object
function F() {} //create an empty function
F.prototype = o; //load the function's prototype with the old object to inherit from
return new F(); //use that function to create a new object and return it.
};
}

This implements inheritance from an existing object when creating a new object.
Crockford says changing o later will change new object.

I also need to create a little javascript lab, a notebook to record code, and to look back on.
