Sorry about that. I hope that the problem is the video quality that mix probably too many subjects in a short time (vscode and julia install, Project creation with pkgskeleton, github repo, Revise).
I think that Julia really shines when you start to use projects.
I have just checked that I can use “run and debug” on a simple julia script:
Note that I use option-O option-J to launch Julia on vscode (Alt-J Alt-O on Linux/Windows)
Hope it helps.
