Reviewer scorecard
“Still the most used JS testing framework. Massive ecosystem of matchers, plugins, and documentation.”
“The fastest way to deploy a serverless function. Write TypeScript in the browser, get an instant URL. No config, no deploy step.”
“Vitest does everything Jest does faster with better ESM support. New projects should start with Vitest.”
“Brilliant for prototyping, webhooks, and small automations. The social aspect adds unexpected value — fork and remix.”
“Jest defined modern JS testing but Vitest is the future. The migration is happening steadily.”
“Val Town is what serverless should have been — write code, it runs. The social coding model adds a new dimension.”
