Working with URL Module

const u = new URL("https://user:pw@host:8080/p/q?x=1#frag");
console.log(u.protocol, u.hostname, u.pathname, u.search);

const p = new URLSearchParams({ a: "1", b: "2" });
p.append("a", "3");
console.log(p.toString()); // a=1&b=2&a=3
for (const [k, v] of p) console.log(k, v);

const u = new URL("https://x.com/p#section-2");
u.hash = "#section-3";
console.log(u.href);

const u = new URL("/api/users", "https://example.com");
u.searchParams.set("page", "1");
u.searchParams.set("q", "ada lovelace");
console.log(u.href);
