Thank you very much for the instruction. It went smoothly. I just had to additionally run
jag setup
which I was clearly told by jag run ...
Very nice experience so far.
One issue I have is that when I use UTF-8 characters in strings they don't show up correctly when the program outputs them to console which also uses UTF-8.
Not sure if I should configure jag somehow to make it work?
With exactly the same setup (editor/console) I have no encoding issues with javascript or python.
What's weirder, console in MINGW64 git bash window (directly, but not through Visual Studio Code) works just fine, even if I launch cmd or powershell in this gitbash window it still works fine.
Switching windows to UTF-8 systemwide through intl.cpl seems to help.
Still weird that other environments don't require this.
