const urlString = "https://example.com/path?id=123&sort=asc";
const url = new URL(urlString);

console.log(url.hostname); // "example.com"
console.log(url.pathname); // "/path"

// Read parameters
const id = url.searchParams.get("id"); // "123"

// Add/Edit parameters
url.searchParams.set("new", "value");
console.log(url.toString());

from urllib.parse import urlparse, parse_qs

url_string = "https://example.com/path?id=123&sort=asc"
parsed = urlparse(url_string)

print(parsed.hostname) # "example.com"
print(parsed.path)     # "/path"

# Parameters (returns dictionary with lists)
params = parse_qs(parsed.query)
print(params['id'][0]) # "123"
