set and get array inside cookie in javascript

JSON encode it, effectively producing a string like "{name:'myname',age:'myage'}"
which you put in a cookie, retrieve when needed and decode back into a 
JavaScript array/object.

Example - store array in a cookie:
----------------------------------
var arr = ['foo', 'bar', 'baz'];
var json_str = JSON.stringify(arr);
createCookie('mycookie', json_str);

Later on, to retrieve the cookie's contents as an array:
--------------------------------------------------------
var json_str = getCookie('mycookie');
var arr = JSON.parse(json_str);
