[noud]

I use vim for almost all my development. I'm using vim ranging from small projects (<10k lines) to very large projects (>10M lines). I never experienced vim to hinder me understanding large projects, nor does it slow me down. There are no features in VSCode (or equivalent) that I'm missing in vim. Actually it's the opposite: the learning curve is steep, but when I was comfortable enough with all the vim key bindings and features, development actually got faster and better using vim compared to using VSCode equivalents. It forces me to think more before I start coding.

I do need to code in VSCode sometimes when it's work related though.
