How to Debug Typescript and Hit Breakpoints | 2018
https://www.youtube.com/watch?v=Jhp3_VJVx2w


It looks like TypeScript breakpoints can be set with VS Code, https://www.youtube.com/watch?v=H1lgYojMCaQ , however I am not sure about Atom. I see mention here: https://github.com/colelawrence/atom-typescript , but not in the main repo: https://github.com/TypeStrong/atom-typescript .
I do see explicit mention in vscode: https://github.com/microsoft/vscode/issues/107615 . . I am currently running Atom and I am considering VSCode because I am struggling to find documentation on how to set breakpoints in atom with the atom-typescript repo and I cannot find others beyond an old fork of the atom-typescript repo. (edited)

I found this useful: (VS Code - Debugging) https://www.youtube.com/watch?v=6cOsxaNC06c
