You are reading just a little too much into it:..

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
