This is just a fan post of why I think VS Code can make a great platform to develop packages for.
Uses Monaco
The Monaco editor is a thing of beauty. There are other great OSS web based editors out there. But there is only so much were a non day job financed OSS developer can support code that other OSS developers write. A recent example is VSCodes ligature font support that is absent in others.
Monaco Extensions
Having a great list of extensions written by devs at Microsoft and having this list grow over time is very encouraging.
Split View
Always good to have, especially for large files.
Diff View
Nice!
Debugger
Only recent OSS editor that gives this workflow the love it deserves
Tooltips
Tooltips that show both the error and the type information. Sign me up.
