Javascript or Jquery - for each on this array

Question

See a screenshot of my returned data i did a console.log on which i need to do a for each on.

array

i have been trying things like this to no avail...?

for (var point in arrayLatLngPoints)
{
    addMarkers(point.timestamp, point.lat, point.lng, point.timestamp, strUserName, pathColour);
}

What's assigned to point inside the loop?

Don't use for..in to loop an array, use normal for loop instead.

for (var i = 0; i < arrayLatLngPoints.length; i++)
{
    var point = arrayLatLngPoints[i];
    addMarkers(point.timestamp, point.lat, point.lng, point.timestamp, strUserName, pathColour);
}

I think a brief explanation as to why they shouldn't use for..in to iterate over an array would make this answer a lot better.

Good info in developer.mozilla.org/en/JavaScript/Reference/Statements/… for why not to use for..in
