Reviewer scorecard
“This fills a real gap in the ecosystem. Worth adopting early.”
“Been using this for 3 months — it's become indispensable.”
“Jest defined modern JS testing but Vitest is the future. The migration is happening steadily.”
“The team ships fast and responds to feedback. Good sign.”
“Vitest does everything Jest does faster with better ESM support. New projects should start with Vitest.”
“Still the most used JS testing framework. Massive ecosystem of matchers, plugins, and documentation.”
