Fit bounds
You can fit the map to the given bounds by calling the fitBounds() method and passing the coordinates of the north-east and south-west points. You can view these points as the top-right and bottom-left corners of a rectangle around which the map will be centered.
map.fitBounds({
northEast: [82.927622, 55.033432],
southWest: [82.921622, 55.027432],
