"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

The square brackets specify an array.  where the { brackets specify an object.  So in the first response you could get back more then 1 object
var json = [{"1":444}];
var j1 = json[0];
alert( j1[1] ); // alert 444

Open in new window

VS :
var j1 = {"1":444};
alert( j1[1] ); // alert 444

Open in new window
