Just reviewing it, Thank you all for your contribution! I appreciate the effort you've put into this commit. The code looks clean and well-organized. Keep up the good work!

As someone who struggled with the debugging lesson, and consequently has limited themselves to primitive 'puts' debugging, is there a reason that this lesson never made it to live? I found it very helpful, despite the lack of a VSCode section.

@ChargrilledChook Do you need/want any help getting this over the finish line?

The debugging content is still one thing that trips up learners currently, and I think this is the last big lift for pulling through the first milestone of the debugging epic. And I think even reaching that milestone and yanking out the current stuff would be a big help for learners.

Apologies for the slow response @josh, I would love to finish this off. Let me get back into context on what's here / what we need to get this off the ground and lets go from there
