title: angularjs filling array from another array
body: <p>(Very new at angularjs)Tried filling array by parsing csv file, as I checked I managed to do it, it perfectly writes everything into $scope.videos array. But when I wanted to split that array on page load by doing init() function, and keep filling it on scroll, but I just get this error, on first try to push array variable.  </p>
