Create a 'do . . . while' loop very basic question

After completing the task associated with this video, I'm looking for a little bit more clarity on the do/while loop.

So, the basic syntax is: 

do {
something; 
} while (some condition)
other code, possibly document.write(), alert(), whatever;

Do you need to add anything (; braces, etc.) after the while (some condition) portion?

Is the closing parenthesis what signals the javascript reader that the while condition is over?

I was hesitant to write anything after the while condition because I was afraid that it would get lumped in as part of the condition.

You simply add a semicolon at the end of the while(condition).

do {
    whatever
}
while (condition) ;

Thanks - I told you it was simple!

I tried various things in the task, and they all passed, so i wasn't sure.
