This will flow your mind
summary
Flow is a static type checker for JavaScript open sourced by Facebook that QuizUp runs on 60,000 lines after about half a year of use and reports fewer regressions and clearer refactorings. It is written in OCaml, maintained by 5–7 maintainers, integrates with Nuclide for Atom and provides auto-complete, type coverage and flows-to-Babel removal via flow-remove-types, but it struggles with opt-in per file exact object checks and modeling non‑native structures like immutable.js pain despite recent active contribution spikes.
