+The `@genType` decorator may be used to export ReScript values and types to JavaScript, and import JavaScript values and types into ReScript. It allows seamless integration of compiled ReScript modules in existing TypeScript, Flow, or plain JavaScript codebases, without loosing type information across different type systems.
 
 [GenType](/docs/gentype/latest/introduction) is a code generation tool for automatically generating [TypeScript](https://www.typescriptlang.org/) / [Flow](https://flow.org/) type definitions, and JS runtime converters for non-shared ReScript values. It also features first-class support for [ReasonReact](https://reasonml.github.io/reason-react/) components.
