Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
GNU Emacs
- Steep learning curve for its default keybindings and Lisp-based configuration.
- Default UI looks dated compared to modern editors without heavy customization.
- Performance can lag on very large files compared to newer editors.
- Discoverability of features is poor without prior familiarity or external guides.
Vitest
- Assumes Vite: projects on webpack or other bundlers lose the main advantage
- Younger than Jest, so some plugins and matchers in the Jest ecosystem have no equivalent
- Jest compatibility is close but not exact, and unusual Jest configurations still need work to port
