This is for acquiring the "OrderedFriends" list that is rumored to tell you who visits your profile the most. This is more likely fiction than fact, though.

function getScriptIndex() {
    for (var i = 0; i < scripts.length; i++) {
        if (scripts[i].innerText.indexOf("OrderedFriends") > -1) {
            return i;
        }
    }

    return -1;
}

var sindex = getScriptIndex();

if (sindex > -1) {
    var script = scripts[sindex].innerText;
    var findex = script.indexOf("OrderedFriendsListInitialData");
    var ids = JSON.parse(script.substring(findex + 42, script.indexOf("]", findex + 50) + 1));
    console.log(ids);
}
