Function orElse

orElse<R extends UnknownTernaryResult, R2 extends UnknownTernaryResult>(
result: R,
alternative: R2,
): R2 | NarrowToOk<R> | NarrowToWarn<R>
Returns the original result if it is Ok, otherwise the provided fallback.
Type Parameters
- R extends UnknownTernaryResult
- R2 extends UnknownTernaryResult
Parameters
- result: R
- alternative: R2
Returns R2 | NarrowToOk<R> | NarrowToWarn<R>
Example
```
const fallback = TernaryResult.ok('fallback');

assert.deepStrictEqual(
  TernaryResult.orElse(TernaryResult.ok('value'), fallback),
  TernaryResult.ok('value'),
);

assert.deepStrictEqual(
  TernaryResult.orElse(TernaryResult.warn('value', 'warn'), fallback),
  TernaryResult.warn('value', 'warn'),
);

assert.deepStrictEqual(
  TernaryResult.orElse(TernaryResult.err('err'), fallback),
  fallback,
);
