Before I learned to use vim (neovim), I used VSCode. I tried to use the vi emulator extension in VSCode, but found it difficult to use due to hotkey conflicts, like trying to do something in vim but it's already a VSCode hotkey that does something else. The "hassle" of setting up Neovim really isn't that bad, and I'm very happy that I've been able to set up a customized experience that's contained in a single dotfile.
