URLSearchParams Constructor — from existing params

new URLSearchParams(url.searchParams) copies params from a URL's searchParams property.

Challenge: Copy a URL's search params and verify the values.

💡 Hints (1)

• Passing url.searchParams to the URLSearchParams constructor creates a snapshot — mutations to the copy do not affect the original URL.
