Help with this JavaScript Code Challenge.

Struggling to figure out how to do this 'do...while' loop. Maybe my brain is fried but I can't figure out what to put in do {}.

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

} while ( secret !== "sesame" ) {
  secret = prompt("What is the secret password?");    
}
document.write("You know the secret password. Welcome.");

The "do" is in the right place.

But the code block that previously came after the while now goes in between the do and the while. The conditional expression after while is now the last part of the loop, so you can put a semicolon after it.

Then, before the loop, just declare secret but don't call prompt to initialize it. Let that happen in the loop.

I'll bet you can get it now without an explicit code spoiler.

Right now you're combining the syntax of a do while loop and a while loop. Move the prompt into the do and end with the while conditional.

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