Function isFixedLengthTuple

isFixedLengthTuple<N extends ArgArr, E>(
len: N,
array: readonly E[],
): array is FixedLengthTuple<N, E>
Checks if an array has a specific length.
Type Parameters
- N extends ArgArr
- E
Parameters
- len: N
- array: readonly E[]
Returns array is FixedLengthTuple<N, E>
Example
```
const pair: readonly number[] = [1, 2] as const;

const triple: readonly number[] = [1, 2, 3] as const;

assert.isTrue(Arr.isFixedLengthTuple(2, pair));

assert.isFalse(Arr.isFixedLengthTuple(2, triple));

if (Arr.isFixedLengthTuple(2, pair)) {
  assert.deepStrictEqual(pair, [1, 2]);
}
