Why VS Code, stack, and stackage?

Editor

A couple of years ago, emacs and vi were the most used editors among Haskell developers, as can be seen in the diagrams below (they cover 2017 - 2020). But as of 2020, VS Code has overtaken them, and is now the most popular editor, and on a very positive trajectory (it's a bit hard to see the labels in the diagrams, but the two leftmost bars in the first two diagrams are for vi and emacs):
