" summary

Compares actual tradeoffs: Flow is a static type checker that you opt into with // @flow and whose server sometimes spawns heavy processes, while TypeScript is a superset language where renaming .js to .ts usually boots it up and the compiler prevents shipping type errors. Shows real numbers (≈20k vs ≈47k GitHub stars, 3k flow-typed vs 22k DefinitelyTyped), notes community and tooling (prefer VS Code, migrate linters), and recommends TypeScript for new projects while acknowledging alternatives like Reason or Elm.
