Is there a way to read standard input with JavaScript?

javascript stdin

I saw this for lots of other languages but not JavaScript.

I'm trying to do problems like: this (codechef.com) and of course the programs need to be able to read standard in like C++ and other languages do.

EDIT: Thanks for the answers. The primary reason I want this functionality is so I can answer the questions on CodeChef; Codechef sends multiple inputs to the files/programs that are the answers (and of course the programs have to respond in the required way for the answer to be correct).

If you use node to act as an interpreter in the terminal, you can use this:

---- name.js ----
var readline = require('readline');

var rl = readline.createInterface({
  input: process.stdin,
  output: process.stdout

});

rl.question(">>What's your name?  ", function(answer) {
   console.log("Hello " + answer);
   rl.close();
});

----- terminal ----
node name.js
