What does the follow code do exactly? What role does it play in the overall scheme of things?

Why do we include the following function?

function print(message) { document.write(message); }

I tried cutting it out, and when I did, the array didn't print to the website. But looking at it, I can't figure out what it does?

Anyone?

This code would just print the passed message to the document.

function print(message) { document.write(message); }

print("Hello");
// prints Hello to the document

In the grander scheme of things, this could be useful if you just wanted to create a function to write things to the console for testing, and don't want to type "console.log" over and over.

function print(message) { console.log(message); }

print("Hello");
// prints Hello to the console

Hope this helps!
