dns.resolveSrv(hostname, callback) function in Node.js

dns.resolveSrv(hostname, callback) function (in node js) sits in a script. Kabir’s job is read notes.txt. Write that first.

Keep dns.resolveSrv(hostname, callback) function (in node js) small. Kabir should finish read notes.txt in a few lines, not a 40-line dump.

dns.resolveSrv(hostname, callback) function (in node js) exists so Kabir can keep read notes.txt correct in a script.

Use dns.resolveSrv(hostname, callback) function (in node js) when read notes.txt must stay clear. If a simpler Node.js step works, use that instead.

dns.resolveSrv(hostname, callback) function (in node js) miss: callback hell, no error-first. Fix it before you talk about advanced Node.js.

Place dns.resolveSrv(hostname, callback) function (in node js) next to nearby Node.js work — (err, data) => … is the link.

One breath for dns.resolveSrv(hostname, callback) function (in node js), then read notes.txt, then callback hell, no error-first. Sit down.

Exam tip

For dns.resolveSrv(hostname, callback) function (in node js): definition + a script + one failure.

Example

  await wait(50);
  console.log("done");
})();

dns.resolveSrv(hostname, callback) function in Node.js — async/await sits on Promises — cleaner than nested callbacks.
