Reviewer scorecard
“Still the most used JS testing framework. Massive ecosystem of matchers, plugins, and documentation.”
“Python script to interactive web app with zero frontend code. The caching and state management work well.”
“Vitest does everything Jest does faster with better ESM support. New projects should start with Vitest.”
“For data scientists who don't want to learn React, Streamlit is the best option. Quick prototyping and dashboards.”
“Jest defined modern JS testing but Vitest is the future. The migration is happening steadily.”
“The UI options are limited compared to real frontend frameworks. Fine for internal tools, not for customer-facing apps.”
