Deep Clone Nested Objects

📖 Usage Example

const arr = [[1, 2], [3, 4]]
const copy = structuredClone(arr)
copy[0][0] = 99
arr[0][0]  // → 1

Use structuredClone() to deep-copy nested arrays without shared references.

Verify that structuredClone() creates deep copies of nested objects, not shallow copies.
