server.listen() Method order: meaning → one server.listen Method step Kabir can write from memory → one limit. Dumping ten features helps nobody.

Without server.listen() Method, a small live site gets messy and server.listen Method on Kabir's board is hard to trust.

Kabir ships server.listen() Method in a small live site. That is the use case worth saying.

Don’t do this with server.listen() Method: skipping the failure case for server.listen Method. Interviewers spot it in ten seconds.

server.listen() Method is not a lonely heading. Kabir ties it to server.listen Method on Kabir's board.

Close server.listen() Method with: “If I skip it, server.listen Method on Kabir's board goes wrong like this: skipping the failure case for server.listen Method.”

Exam tip

Board: server.listen Method on Kabir's board. Dry-run server.listen() Method. Name the trap: skipping the failure case for server.listen Method.

Example

const http = require("http");

const server = http.createServer((req, res) => {
  res.writeHead(200, { "Content-Type": "application/json" });
  res.end(JSON.stringify({ ok: true, path: req.url }));
});

// server.listen(3000);
console.log("handler ready for", "/api/health");
console.log(JSON.stringify({ ok: true, path: "/api/health" }));
