How to convert JSON object to JavaScript array?

Question

I need to convert JSON object string to a JavaScript array.

This my JSON object:

{"2013-01-21":1,"2013-01-22":7}

And I want to have:

var data = new google.visualization.DataTable();
data.addColumn('string', 'Topping');
data.addColumn('number', 'Slices');

data.addRows([
    ['2013-01-21', 1],
    ['2013-01-22', 7]
]);

How can I achieve this?

If you have a well-formed JSON string, you should be able to do

var as = JSON.parse(jstring);

I do this all the time when transfering arrays through AJAX.
