// JSON string returned from the server
var text = '{"items":[{"name":"itemX" ,"price":15},{"name":"itemY","price":25},{"name":"itemZ","price":20}]}';

// Convert the string returned from the server into a JavaScript object.
var object = JSON.parse(text);

// Accessing a specific property value of an item
console.log(object.items[0].name); //itemX

// Extract 'items' in to a separate array
var itemsArray = object.items;
console.log(itemsArray); //[itemObject, itemObject, itemObject]
