In JavaScript, what is the difference between an object and a hash? How do you create one vs the other, and why would you care? Is there a difference between the following code examples?

var kid = {

 name: juni,

 age: 1

}

And:

var kid = new Object();

kid.name = juni;

kid.age = 1;

And:

var kid = new Object();

kid[name] = juni;

kid[age] = 1;

Can you think of any other code example I should illustrate?

The core question here is what is the difference between an object and a hash?
