Function map

map<T, E, U>(
ra: ResultAsyncType<T, E>,
fn: (value: T) => U | Promise<U>,
): ResultAsyncType<U, E>
Transform the success value of a ResultAsync. fn may return a value or a Promise. Errors short-circuit: on err, fn is not called and the error propagates unchanged.

Dual API — works data-first or curried for use in pipe.
Type Parameters
- T
- E
- U
Parameters
- ra: ResultAsyncType<T, E>
- fn: (value: T) => U | Promise<U>
Returns ResultAsyncType<U, E>
Example
```
pipe(
    fetchUser(id),
    ResultAsync.map(user => ({ ...user, name: user.name.trim() })),
  )
```
