Example
```
const emptyNumbers: readonly number[] = [] as const;

const words = ['Ada', 'Lovelace'] as const;

assert.isTrue(Arr.isEmpty(emptyNumbers));

assert.isFalse(Arr.isEmpty(words));

if (Arr.isEmpty(emptyNumbers)) {
  // `isEmpty` narrows to the branded `FixedLengthArray<0, number>`, so the
  // expected value is annotated with the unbranded type.
  assert.deepStrictEqual<readonly number[]>(emptyNumbers, []);
}
