BigInt.asIntN() — 128n wraps

📖 Usage Example

BigInt.asIntN(64, 2n ** 63n)  // → -9223372036854775808n

Use asIntN(64, ...) to simulate 64-bit signed integer overflow behavior.

BigInt.asIntN() 128 in 8-bit

BigInt.asIntN(8, 128n) wraps to -128n because 128 is just above the signed 8-bit max.

Challenge: Verify this specific wrap.
