Debugging in Julia is just decent for the code I have tested. The problem is rather we don’t document all the features we provide, and some of them are essential. This must be improved, because we end-up spending more time guiding users in forums than creating a complete documentation.
Imagine a new user who wants to debug. He starts here: Debugging · Julia in VS Code (julia-vscode.org). They need to imediatelly know all available configs for debbuging and all external tools like Debugger.jl and Infiltrator.jl.
Here is a modest PR in this regard: Minimally document externall debugging tools by MariusDrulea · Pull Request #77 · julia-vscode/docs (github.com).
Improving the docs menu will help as well: Include headings level 3 in the menu, on click · Issue #75 · julia-vscode/docs (github.com)
