A simple "Hello, World!" program written in JavaScript (little playful...couldn't help myself ;)

If you really want it a little more serious (and just bask in the mere thought of sucking the fun out of everything), here it is:

console.log('Hello, world!');

Or, if you would prefer one that is far more feature-filled and complete, check this one out!
