Function flatMap

flatMap<T, U>(maybe: Maybe<T>, fn: (value: T) => Maybe<U>): Maybe<U>
Canonical bind for Maybe. Chains a Maybe-returning step; short-circuits on None. Dual-form.
Type Parameters
- T
- U
Parameters

- fn: (value: T) => Maybe<U>
Returns Maybe<U>
Example
```
flatMap(fromNullable(user), (u) =>
  u.active ? some(u) : none(),
);
```
