Function resultUnwrapOrElse

resultUnwrapOrElse<T, E = Error, U = T>(
result: Result<T, E>,
fallback: (error: E) => U,
): T | U
Extracts the value from a successful result, or computes a fallback from the error.
Type Parameters
- T
- E = Error
- U = T
Parameters
- result: Result<T, E>
  The result to unwrap.
- fallback: (error: E) => U
  Called once, only for Err, with the original failure value.
Returns T | U
The success value or the computed fallback.
Remarks
Returns falsy and nullish success values unchanged. The fallback runs synchronously; exceptions it throws propagate to the caller.
Example
```
resultUnwrapOrElse({ ok: true, value: 42 }, () => 0);    // 42
resultUnwrapOrElse({ ok: false, error: e }, () => -1);   // -1
```
