Help with this example please.

I am just looking for some help with the solution to this example. Also, any help with tips on knowing when to set variable/which variables to set prior to running the loop. Just having some difficulty putting it all together. Thank you.

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

document.write("You know the secret password. Welcome.");

Hi Alicia, the challenge asks you to use a while loop to keep asking the user for the password until they provide the correct answer "sesame". We use a while loop because you set a condition and it will keep looping through the code until the condition has changed e.g the correct password has been provided. For this code challenge we use the while loop in the following way:

while ( secret !== "sesame" ) { //while the password is NOT equal to "sesame"
  secret = prompt("What is the secret password?");    //ask the user to provide a password
}

When the user provides the correct password ("sesame") the while loop will be exited and then the code following it will be executed, in this case:

document.write("You know the secret password. Welcome.");

Hope that helps!!
