Why do I get this error? Bummer: There was an error with your code: SyntaxError: Parse error

Please see script.js

script.js
var secret = prompt("What is the secret password?");

do ( secret !== "sesame" ) {
  secret = prompt("What is the secret password?");    
}   while (!"sesame")

document.write("You know the secret password. Welcome.");

At first glance, I'd guess it was having an expression between the "do" and the brace starting the code block.

And the expression !"sesame" will always be "false", so it's probably not what you really want there.

Also, one of the reasons a "do" is a good structure here is so you don't have to ask the question in two places. Before the loop you only need to declare the variable.

Yes, I've got it now. I think I was confusing the syntax of Do loops with While loops. Thanks for your help.

It takes a bit of getting used to, that was the whole point of this coding challenge.

Happy coding!
