If I go through the whole API reference of WAB, do I still need to be a master at ArcGIS API for JS in order to develop custom Widgets ?
Hey Humza,
You will have to have an good knowledge of how the ArcGIS javascript API works and how javascript works in general. Once you understand that I would move over and look at how the WAB works. Since the WAB builder is built upon the javascript API, you will use a lot of it to create custom widgets.
