Why won't this work? do while loops JS

var secret = prompt("what is the secret password");

do { alert(secret); if (secret === "sesame") { secret = true; } }

First off, i got the right answer, but I wanted to know why this won't work. I don't know why I have to add the prompt inside the dowhile loop.

Also, can someone tell me how to copy/paste code?

If you put your code inside three tick marks (the unshifted tilde key) it should format correctly.

// I am code

For best results put the ``` on it's own line.

tick tick tick

pasted code

tick tick tick

The "Markdown Cheatsheet" has more info on this I believe.

I think you want something more along these lines.

var secret; // declare the secret variable so you can use it inside the loop
do { // always do the following code block at least once
  secret = prompt("what is the secret password?"); // execute the code inside the block...
} while (secret !== "sesame"); // and THEN evaluate if secret is equal to 'sesame' - if not, run the block again until it is.
document.write("You know the secret password. Welcome."); // once secret = sesame, write to the document
