Rotation and movement applied to other objects

Hi everyone. Is there a way to have an object “mirror” another object using scripting? Thanks.

var otherObject : Transform;

function LateUpdate () {
    transform.position = otherObject.position;
    transform.rotation = otherObject.rotation;
    transform.localScale = otherObject.localScale;
}

Add it as a child of the first object in the inspector or through code.
