Visual Studio Code is a wonderful text editor. But it's far from being a full-featured IDE.
Like most IDE's, it is a mediocre text editor with a bunch of compelling (for certain workflows) tooling for project and build management, debugger, etc. Plus usable introspection. As a text editor though, a solid C+ at best.
Is VS Code someone doing something radically different?
Completely open source, rich plugin/extension community. Pretty much has become the editor of choice if you're working on node or go... more than decent with other platforms, and as a general editor. There are extensions to improve workflows, but all optional extensions.
I have git history, git lense, eslint, docker, c# (works for .net core), go, jest, npm, npm intellisense, yandex-translate (makes vscode worthwhile by itself), and a couple others.
I don't think I can go back... having the treeview, git integration, integrated console, it's all just way awesome to say the least.
