What is the analog of "Networkview.ismine" method in unityscript?

The problem is when I create a server and connect to it, two players have appeared. When I try to move one of them, both players move simultaneously in the same direction.

All the scripts are written in unityscript, so I need analog of Network.isMine method in unityscript, which returns boolean

Does someone know this?

NetworkView.isMine was available in UnityScript. That of course is in versions of Unity prior to both the legacy networking and UnityScript having been removed.
