How is writing something in vim faster? You can have the same bindings in many IDEs.
Anyway, if you don't care about all that, you can get a similar effect by turning off intellisense (or equivalent) in your IDE while you write, then turn it back on at the end to get what you just wrote to compile. I do this sometimes in Android Studio.
The VSCode Neovim extension makes neovim run as its backend, while giving you all the IntelliSense etc of VSCode. I can’t tell exactly you how it affects responsiveness as I only toy around with it, but it does feel noticeably better in some aspects...yet maybe occasionally glitchy?
Anyway it’s pretty interesting, especially if you’re already using neovim anyway.
