JSON Format

JSON is a data structure format. It used for data transfer. So, what it's look like? It's very simillar like object literal, but more strict in rule. It just allows key as string, but the value is whatever - not just data but also function. This is a map like data structure.
To initialize it, use:

var data = {

    "name": "lady gaga",

    "city": "new york",

    "age": 24,

    "album": ["fame","fame monster"]

};

To access it, use dot operator:

alert(data.name);        // lady gaga

alert(data.age);         // 24

alert(data.album[1]);    // fame monster

or use [ ] operator:

alert(data['name']);

alert(data['age']);
alert(data['album'][1]);    // fame monster
