Confusion on whether there is anything Ajax can do but JavaScript cannot do?

Using AJAX we can change part of a JSP page without reloading the entire page. But cant this be done using simple Javascipt. E.g of a AJAX task is populating cities based on states in dropdown.But cant this be done using Javascript.So what is there in AJAX which simple javascript cannot do?

Thanks.

When you say AJAX, you mean you're sending a request to the server, getting back a response, and using the response to update the DOM, i.e. part of the HTML page. JavaScript is involved of course. In fact it is the J in AJAX.

True to a certain degree, JavaScript *can* be used to rewrite the HTML contents (the DOM) in the browser.

Now how would you say access a back-end business process, update a monthly sales figure without an AJAX
call back to the application server, return the data and rewrite it using Ajax.

They work together.

As Ajax is part of JavaScript it's a pointless question. It's like asking if there's something the java.net classes can do that Java cannot.
