Answer 1

// 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]

If you're getting this as a string:

var json = JSON.parse(my_json_string)

Then,

var keys = Object.keys(json);
var values = [];
for(var i = 0; i < keys.length; i++){
 values.push(json[keys[i]]);
}
