I don't know What is missing in the while loop. Please help me!

I did the following:

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

But it is incorrect. What am I doing wrong? Thanks!

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

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

You only want the loop to keep repeating while the secret is not equal to the word sesame, and it's considered a best practice to use the strict not equal to !== operator as well.

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

while (secret !== "sesame")
{
  secret = prompt("What is the secret password?");
}

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