Angular – Simple Typewriter Effect?

There is a beautiful typewriter directive already written, but I'm looking for something more simple, that just adds each letter after an interval. I can't get this to work. It s

Solution 1:

Here is an alternate way.

var content = "contentcontentcontentcontentcontentcontentcontentcontentcontentcontentcontent";

$scope.type = "";
var i=0;

var timer = $interval(function(){
    if(i<content.length)
        $scope.type += content[i];
      else$interval.cancel(timer);

     i++; 
     $scope.$apply();
}, 100);

Solution 2:

Update - This is working for me, not sure if it could be more efficient...

var time = 0;
var addLetter = function(i) {
    $scope.string2 = $scope.string.substr(0, i);
};
for (var i = 0, len = $scope.string.length; i < len + 1; i++) {
    time = time + 50;
    (function(time, i) {
        $timeout(function() {
            addLetter(i);
        }, (time));
    })(time, i);
}
