Its a simplified version of a problem from work a while ago where we had to generate ui from lots of csv files. The last dev on it was taking weeks, but with vim I was able to come in and finish the boilerplate instantly. (We were commited to non-dynamic ui at that point, I think I made the right play especially with how we ended up using it).
Vim is, in my opinion, inferior to an ide or a good text editor, but if you have it as a plugin you get the best of both worlds and vim suddenly can do... basically anything you can think of. Like here's putting a breakpoint on every line in a file
The best part of vim in an ide is when you're pair programming and you do something fancy, and your friend says "Wait, go back, howd you do that??"
