A community-maintained reference document comparing the syntax, usage, and usability of TypeScript and Flow type checkers. It catalogs differences in IDE support, type safety, expressiveness, and language features between the two systems.

Use cases

  • compare typescript and flow syntax differences
  • decide between flow and typescript for a project
  • migrate from flow to typescript
  • find flow equivalents of typescript features
  • learn how flow type soundness differs from typescript
  • reference for type system syntax in javascript

When to choose

  • you are evaluating TypeScript vs Flow for a JavaScript codebase
  • you need a side-by-side syntax reference while migrating between the two type systems
  • you want a quick overview of usability and tooling differences

When to avoid

  • you need up-to-date coverage of recent TypeScript or Flow versions (document targets TS 3.7 and Flow 0.101)
  • you need a type checker or tool rather than documentation
  • you need benchmarks of type-checking performance (marked as missing)
