JS Practice — Built-in Objects

Set clear() — size before vs after

📖 Usage Example

const s = new Set([1, 2, 3])
s.clear()
console.log(s.size) // → 0

Use Set.clear() to remove all values from the set.

Set.prototype.clear()

size goes from non-zero to zero after clear().

Challenge: Verify that size changes from 3 to 0 after clear().
