Hi Sasikumar,

Yes, you can build your own iterator directive. This is not as simple as it sounds though. What is it you need to do, that you are not getting done with ngRepeat?

Hi Sander Elias,

I done with ngRepeat so far but i red one article about optimizing angular js apps. In that article   "The ng-repeat directive is most likely the worst offender for performance concerns, which means it can easily be abused. An ng-repeat likely deals with Arrays of $scope Objects and this hammers the $digest cycle’s performance."
they told ngRepaet involves no of $watcher method to $digest through our application. So i'm looking for an alternate option for ngRepat if  possible.

As u said it is possible by building our  own directive can u give me some sample code for that so that i can able to understand easily.

Thanks & Regards,

Hi Sasikumar,

Well, you can look into the source of ngRepeat itself. Sure you can create a simple iterator yourself, but then again, if you want to keep it in sync with your data, you need to watch the data. It might pay of if you have a really large table you have to show, but in my opinion large tables are usually a bad user interface. Science shows us that more then 150 to 200 elements in a UI only add confusion to the user.  

All in all, I would not bother unless you really can't avoid it.
