Function isEmptyTuple

isEmptyTuple<E>(array: readonly E[]): array is readonly []
Type guard that checks if an array is empty, narrowing it to the structural empty tuple.

This is the structural counterpart of isEmpty: it narrows to readonly [] rather than to the branded FixedLengthArray<0, E>. Prefer isEmpty unless you specifically need the structural type.
Type Parameters
- E
  The element type.
Parameters
- array: readonly E[]
  The array to check.
Returns array is readonly []
true if array.length === 0. When true, TypeScript narrows array to readonly [].
Example
```
const values: readonly number[] = [] as const;

assert.isTrue(Arr.isEmptyTuple(values));

assert.isFalse(Arr.isEmptyTuple([1] as const));
```
