In the example mentionned in the video, why couldn't we do that instead of the do while loop?

const userResponse = prompt("What is the password?"); //I could validate the prompt dialog in doing that const password = "Vic Mercier"; while(userResponse !== password){ alert("Please try again!"); }

Note that neither "userResponse" nor "password" are modified in the loop. If none of the terms that control a loop are changed inside the loop, then the loop will go on forever.
