How to use the gojs.Set function in gojs

To help you get started, we’ve selected a few gojs examples, based on popular ways it is used in public projects.

let bestvert: any = null;
      let it = coll.iterator;
      while (it.next()) {
        let v = it.value;
        let dist = v.distance;
        if (dist < bestdist) {
          bestdist = dist;
          bestvert = v;
        }
      }
      return bestvert;
    }

    // keep track of vertexes we have finished examining;
    // this avoids unnecessary traversals and helps keep the SEEN collection small
    let finished = new go.Set(RadialVertex);
    while (seen.count > 0) {
      // look at the unfinished vertex with the shortest distance so far
      let least = leastVertex(seen);
      let leastdist = least.distance;
      // by the end of this loop we will have finished examining this LEAST vertex
      seen.remove(least);
      finished.add(least);
      // look at all edges connected with this vertex
      least.edges.each(function(e: any) {
        let neighbor = e.getOtherVertex(least);
        // skip vertexes that we have finished
        if (finished.contains(neighbor)) {return; }
        let neighbordist = neighbor.distance;
        // assume "distance" along a link is unitary, but could be any non-negative number.
        let dist = leastdist + 1;
        if (dist < neighbordist) {
