Hello, World!

It has been a tradition, in computer programming, as a first step into a larger world, to devise a trivial bit of code that outputs the statement, “Hello, World!“ for all to see. Here is one such instance, in a bit of a roundabout way:

(function() {
  "use strict";
  var a = "Hell", 
      b = "o, W", 
      c = "orld";
  alert(a + b + c + "!");
} )();

That’s JavaScript. In Firefox (or Chrome), press F12 to open your Console, copy and paste that code, press Enter, and see what happens.
