ok, there are two different loops. do while and while loops. this example is a do while. Why the do key word come 1st.

the different between the do?

do while will go through the loop at least one time.

do{ the code in there will run atleast one time } while{ is the conditions is met the do code will run again }

now a while loop while{the code in there will run in a loop untel the conditions is false }

I hope this help you. Happy coding

The word "prompt" should not appear after the "while", that's a syntax error.

Also, one of the advantages of the "do...while" style is you will only need to call "prompt" once (inside the loop). So outside the loop you just need to declare the variable.
