Applying a numeric example for do-while loop to an alphanumeric question

How do I take the numeric example of do-while loop in video and apply it to a alphanumeric question, please help!

script.js 
let secret = prompt("What is the secret password?");
let password='sesame';
do{
  secret = ` `;
  alert("You know the secret password. Welcome!");
} while(secret!==password)

Hi Clare!

This passes:

// Display the prompt dialogue while the value assigned to `secret` is not equal to "sesame"
let secret;
do {
  secret = prompt("What is the secret password?");
} while(secret !== 'sesame')
// This should run after the loop is done executing
alert("You know the secret password. Welcome!");

The trick is declaring "let secret" outside the do block.

If it is declared inside the do block its scope is lost to the while condition and can't be found.

I hope that helps.

Stay safe and happy coding!
