“Jest-compatible API with Vite's speed. ESM and TypeScript work without configuration. The watch mode is instant.”
“Babel is effectively replaced. SWC's speed improvement is dramatic and the compatibility is excellent.”
“If you're using Vite, Vitest is the obvious choice. Even without Vite, the speed improvement over Jest is significant.”
“SWC is the invisible engine powering modern JS tooling. Rust compilation speed enables new tool architectures.”
“Vitest is replacing Jest as the default test runner. Speed and modern JavaScript support drive the migration.”
