I use this loop for create map markers (1000 points):

```
var markers = {};
for (var i = 0; i < items.data.data.length; i++) {
    latVal = items.data.data[i].lat;
    lngVal = items.data.data[i].lng;
    ikona = icons.infost;
    message = "<b>" + items.data.data[i].name + "</b>";
    markers[i] = {'group': 'cmp', 'lat' : eval(latVal), 'lng' : eval(lngVal), 'icon' : ikona, 'message' : message};
}
$scope.Markers = markers;

```

how I can improve the for loop speed in angularjs (currently it takes almost 10s)?
