TypeScript · Senior · Question 75 of 75

Why is it risky to type an API client with generics alone, like `get<T>(url): Promise<T>`?

✓Correct answer: The generic is an unchecked assertion - any T compiles, even if the server returns something else
2Generics make requests slower
3Promise<T> can't be awaited

Explanation

Generate types from an OpenAPI schema or validate responses with a schema so the declared type matches reality.
