Get key value of dictionary

Question

How do I get the value from a javascript dictionary? (I don't even know if it's called a dictionary in javascript)

I get the following object (friends) from the facebook sdk. How do I, for example, loop through the names?

{data: [{id: "xxxxx", name: "Friend name"}, {id: "xxxxx", name: "Friend name"}]}

In JavaScript dictionaries are objects. To access object properties you may use either dot notation or square brackets notation. To iterate an array you may use simple for loop.

var obj = {
        data: [{
            id: "xxxxx",
            name: "Friend name"
        }, {
            id: "xxxxx",
            name: "Friend name"
        }]
    };

for (var i = 0, len = obj.data.length; i < len; i++) {
    console.log(obj.data[i].name);
}
