import readline from "node:readline";

const rl = readline.createInterface({
  input: process.stdin,
  output: process.stdout,
});

const answer = await new Promise((resolve) => {
  rl.question("Your name? ", resolve);
});
rl.close();

console.log(`Hello ${answer}`);

Caveats

ES module with top-level await: run as .mjs, or set type module in package.json. Needs a TTY. Empty input is an empty string, not null.
