Custom 2D Widget Development with JavaScript

Anonymous User

Hello All,

I want to build a custom 2D widget from scratch for use with a web map, but I am confused about which JavaScript API to use. I noticed there is a 3.x version and a 4.x version. I also noticed that the 3.x version has references to jimu and dojo in the example code, but it doesn't look like 4.x does according to the 4.x documentation. I am trying to learn based on the tutorial at this link: Create a custom in-panel widget—ArcGIS Web AppBuilder (Developer Edition) | ArcGIS for Developers My questions are:

Which version should I use?
