This question already has an answer here:

In desktop, there is http://pro.arcgis.com/en/pro-app/help/editing/create-arc-segments-and-curves.htm to create arc and curves, but I can't find any tutorial about how to make and create arc or curves on ArcGIS API for Javascript.

Is there any way to do that?
