How to apply variable to next item in array?

I want to make it to where destination is points[0]. if transform.position == points[1], then destination = points[2]. if the object is at the same position as destination, destination is set to the next point in the points[] array. How would i do this since the amount of points[] can varry?

  int p = points.Length;
         if (go && p > 2)
         {
             float step = speed * Time.deltaTime;
             transform.position = Vector3.MoveTowards(transform.position, destination.position, step);
 
             if (transform.position == destination.position)
             {
                 //var cPoint = points[0];
                 destination = points[1];
             }
             
 
 
         }
