Can someone explain to me getElementByID and the function(message)?

Hey Alex, You can add document.write(variable); but one benefit of having a function that manipulates the DOM is it gives you the ability to style the output a certain way without having to add that style to the JavaScript. You can leave the style in the CSS.

The message from function(message) is an argument holder so that you can later call the function with a specific argument.

For example:

function print(message){
  var outputDiv = document.getElementById('someDiv');
  outputDiv.innerHTML = message;
}

bananas = 'This ish is bananas, BANANAS!'
print(bananas);

In order to fire off that print function, I need to supply some kind of message. I create a message, in this case a message called bananas, and drop it into the function.

I can later create a different message called something else and drop it into the print function for it to do the same thing.

Does that make sense? I'm still learning as well, but this is how I understand it.

Best, Mike
