Reviewer scorecard
“Still the most used JS testing framework. Massive ecosystem of matchers, plugins, and documentation.”
“20x faster than Babel with full compatibility. Used by Next.js which validates production readiness.”
“Vitest does everything Jest does faster with better ESM support. New projects should start with Vitest.”
“Babel is effectively replaced. SWC's speed improvement is dramatic and the compatibility is excellent.”
“Jest defined modern JS testing but Vitest is the future. The migration is happening steadily.”
“SWC is the invisible engine powering modern JS tooling. Rust compilation speed enables new tool architectures.”
