It just change the content of the document and writes the message passed as parameter to your function.

Hello Brandon,

That function will take the value passed in as "message" and print it to the document.

For example, if I passed "Hello, Brandon" to the function like this.

print('Hello, Brandon');

document.write(message) will add 'Hello, Brandon' to the document associated with the JavaScript.

I hope this helps.
