How are you guys all working in one language?

I work on a stack that has ruby on rails on the backend, javascript on the frontend, .NET Core apps to do data transformation, and some NodeJS thrown in there, too. I have to switch back and forth between these projects regularly. There is no other tool like VS Code that provides me the flexibility to have snippets and highlighting and the things I need to maintain these projects, while also giving me the flexibility to switch between languages and syntax on the fly without having to wait 20 minutes just for the IDE to load up.
