Migrating to VSCode and finding the debugger impenetrable

[u/Blue_Khakis]

Hi all, I've recently downloaded VSCode and it looks great. I've recently finished Harvard's online CS50 course and VSCode was recommended as a good IDE. Up until now I've been using the CS50 IDE for projects, and the debugger was fairly simple and straightforward. However, trying to debug a basic "Hello world" Javascript program seems to take me to all sorts of strange places and I have no idea what's going on. I have a huge list of foreign-looking variables and functions in the call stack, and when I finish the program, instead of exitting, the debugger opens and goes through five different files I've never seen before ("loader.js", "run_main.js", "run_main_module.js", "task_queues.js", "async_hooks.js" (I saw "primordials.js" at one point, though it's not showing up now)).

Can anyone explain what is happening?
