URLSearchParams#append() — size increases

📖 Usage Example

const p = new URLSearchParams('a=1&b=2')
p.delete('a')
p.toString()  // → 'b=2'

delete() removes all values for a given key from the parameters.

URLSearchParams#append() — size

Each call to append() increases the size by 1.

Challenge: Verify that repeated append() calls increase the size.
