polygon pointcollection

How do you find the number of points in a polygon? PointCollection is the object in ArcGIS api for Silverlight. This object is not working in ArcGIS api for javascript 3.19

Here's one way to do it. Given a polygon (feature), this returns the point count for each of a polygon's rings

for (var i; i < feature.geometry.rings.length; i++) {
   console.log("Ring" + i + ": " + feature.geometry.rings[i].length + " points");
}‍‍‍

It works. Thanks.

I am converting an ArcGIS api for Silverlight application to ArcGIS api for JavaScript 3.19 using MVC5. Why is the JavaScript 3.19 intellisense not displaying properly?
