Confused on the function - function print(html) { document.write(html); }

Hi, i am still a bit confused to how does this ode works - function print(html) { document.write(html); }

Why i am confused is that, I understand the print() method "prints" the contents of the current window. but what is "html" in this case? is it another method?

Thanks in advance

In this case "html" is just the parameter name that stands for whatever you pass when you call the "print" function. All this function does is pass the same thing on to the "document.write" function, so effectively "print" is just another name for "document.write".

Thanks Steven Parker for your answer. just to confirm can you also just write the same function but without the "html"? like below? function print() { document.write(); }

or do we need it in order to run document.write() ?

You must have some parameter name, it cannot be blank. But it doesn't have to be "html", you can use any name you want.

Thanks! Steven Parker it all makes sense now!
