How to load data in Yandex maps with ajax?

Question

JavaScript

There is a Yandex map on it, tags are added through the collections. I can’t find it in the docks or in the sandbox, how to track those that have disappeared from the scope and remove and ajax-om add those that have appeared when moving the map. With the server part it is clear. I don’t understand how to keep track of which ones are out of sight, which part has appeared. And share your experience whether it is necessary to remove the missing ones from the visibility zone, so that later they would not be loaded again. How much does it slow down the browser?
