Javascript: do while versus while

Is there any real difference between do-while loops and while loops in Javascript? I know that do-while executes the code block before checking the condition, and while checks the condition first, but are there any other differences like performance?

Yes, as you said do-while will execute the code block at least once even when the condition fails.

Other than functional difference, there should be no performance difference.
