At the Esri Arcade
I don’t use Esri software anymore so I can’t play with it but it is a logical solution to their problem of having to write code to work with data in different platforms. Theoretically one can now use Arcade to author and render maps and let the Esri software handle the rest. I’d wait to see what happens with Arcade and the eventual 1.x release. It’s the Esri Web ADF talking but…
Wait, another proprietary programing language?
