Code Challenge Question: Do..While Loop

Why does it say the prompt() needs to be inside the loop? Why can't i just call 'secret' in the loop?

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

do{
  secret ;
}
while ( secret !== "sesame" ) 
document.write("You know the secret password. Welcome.");

when you say var secret = prompt(...), the variable secret gets assigned the return value of the prompt function; in other words, the user would only every be prompted once at the beginning. secret isn't an alias for the prompt action, it's the result of the prompt, so the variable would never be changed, and so it would be an infinite loop!
