How to determine the parameters of Yandex Maps depending on the marks on the map?

Question

JavaScript

When we add a Yandex map to the site, we indicate the coordinates of the center and the zoom, but let's say I have three marks on the map and I need the map to be configured so that ideally all these three marks fall and that's it. I see it this way - before rendering, you need to determine, based on the labels, somehow the middle and the zoom. I have not worked with geodata before, if anyone has experience, please tell me how best to do it all.

Answer 1

map.setBounds(map.geoObjects.getBounds())

Or, if there are other marks on the map besides the ones you are interested in, put the necessary marks into a GeoObjectCollection and call getBounds on this collection:
