tl;dr Add this to your user or workspace settings:
"": "C:/Windows/sysnative/bash.exe",

I really like VSC for javascript development. One of the great features is the integrated terminal.

Now if you are still using git bash for running your commands you can use it too just change bash.exe above to the location of your git\bin\bash.exe file.

The above will automatically start a terminal logged into your windows Linux sub-system.

Using the new Windows bash as your integrated terminal in Visual Studio Code (VSC)
