JMP 201 AJAX & JSON
JSON (JavaScript Object Notation) looks pretty cool, basically a way to standardize data layout so JavaScript can work with it. Also like it because it uses dot notation.
AJAX (Asynchronous JavaScript and XML) is a set of extensions to JavaScript that allow it to do cool, client-side stuff that allows manipulation of the on-screen page with little or now trips back to the browser.
JQuery (www.jquery.com) is a JavaScript library that lets you easily do all the JSON stuff in an AJAX-enabled browsers with some quick library calls.
