Convert ArcGis Geographic coordinates Lat Long wkid: 4326 to predicted coordinates wkid: 102000/3857

When using the JS ArcGis API, you can create a point in ArcGis with lat and for a long time as

var testPoint = new Point(-98, 38);

or

var testPoint = new Point(-98, 38, new SpatialReference({ wkid: 4326 }));

and convert it to another SR so that its x and y are changed automatically? For instance. to wkid 102000/3857?

CONTEXT: (maybe you can find a workaround)

I use heatmap.js to draw heatmapLayers on ArcGis maps. I found several examples and the way this API uses data uses a variable datain the following format:

var data = [
  {
    attributes: {},
    geometry: {
      spatialReference: { wkid: ****},
      type: "point",
      x: -40,
      y: 50
    }
  },
  {another point....}
];

The API itself does some sorting on a variable dataand then uses this method

screenGeometry = esri.geometry.toScreenGeometry(this._map.extent, this._map.width, this._map.height, parsedData.data[xParsed][yParsed].dataPoint);

to convert the analyzed point ( parsedData.data[xParsed][yParsed].dataPoint) before finally drawing a heat map.
