 ## TypeScript type helpers for Amplify Data
 
-When using TypeScript, you frequently need to specify data model types for type generics. For instance, with React's `useState`, you provide a type in TypeScript to ensure type-safety in your component code using the state. Use the `Schema["MODEL_NAME"]["type"]` pattern to get TypeScript types for the shapes of data models returned from the backend API. This allows you to get consumable TypeScript types for the shapes of the data model return values coming from the backend API.
