Promise Types
Promise Types
π¨βπΌ Perfect! Notice how TypeScript infers that
user is of type User and
products is of type Array<Product> after awaiting. The type system understands
that await unwraps the Promise.π¦ Explicit return type annotations on async functions are especially helpful
when:
- The function body is complex
- You want to document the contract
- You're creating a library API
TypeScript will still infer types, but explicit annotations make your code
self-documenting.
