Try using it this way:

var getRandomWord = (function () {
  var gameWordArray = [];
  gameWordArray.push("monitor");
  gameWordArray.push("program");
  gameWordArray.push("application");
  gameWordArray.push("keyboard");
  gameWordArray.push("javascript");
  gameWordArray.push("gaming");
  gameWordArray.push("network");
  return function () {
    var randNum, finalWord;
    randNum = Math.floor(Math.random() * gameWordArray.length);
    finalWord = gameWordArray[randNum];
    return finalWord;
  };
})();

Instead of declaring an array with a predefined length, you might as well declare an empty one and add values to the end of it (with .push()). You could've also declared the array like:

var gameWordArray = ["monitor", "program", ...];

You were trying to print word (which I renamed to getRandomWord), which was/is a function. You probably meant to use console.log(gameWordArray[randno]), which should work.

roll==name will always return false because in that case you are checking whether they refer to the same memory location.

Use if (roll.equals(name)) instead.
