A simple number guessing game in node.js

gra.js

//var process = require('process');
var readline = require('readline');

var randomNumber = Math.round(Math.random() * 10);
var lives = 5;

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

terminal.setPrompt('Guess the number! (0-10): ');
terminal.prompt();
terminal.on('line', function(answer)
{
  var answerNum = parseInt(answer);

  if (answerNum > randomNumber)
  {
    console.log('Too high!');
    console.log('You have '+lives+' lives left');
  }

  else if (answerNum < randomNumber)

    console.log('You have '+lives+' lives left');
  }

  else if (answerNum === randomNumber)

    console.log('W I N N E R ! ! !');
    console.log('You lost only '+ (6-lives) + ' lives');
    process.exit(0);
  }

  else
  {
    console.log("That wasn't a number I recognise");
    console.log('You have '+lives+' lives');
  }
