Practical Confidence: Using Types to Help Your Computer Help You
summary
Static typing via Flow claims to catch undefined errors, enforce API shapes, and speed safe refactors while emitting no runtime code; annotations are stripped and editor integrations give fast editor feedback and much better autocomplete and jump-to-definition. Structural vs nominal types, union types and type inference minimize annotation burden; optional "any" and configurable suppressions like flow fix me support incremental adoption. A community flow-typed repo supplies library defs so adoption scales without rewriting every dependency.
