While infinite loop

I don't know how to fix it

var secret = prompt("What is the secret password?"); while (secret === "sesame") { document.write("You know the secret password. Welcome."); }

app.js 
var secret = prompt("What is the secret password?");
while (secret === "sesame") {
  document.write("You know the secret password. Welcome.");
}

Hey Irene,

Your loop is happening when the word is "sesame", when the word is "sesame" it should stop.

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.");

First we declare the variable secret which will hold the first value of the prompt window. If the value of the variable secret is different than "sesame" the while loop will execute and show a prompt window again, then it rewrites the value of the secret variable with the new value value introduced in the promp window. If the secret value is equals to 'sesame' the while loop will stop executing and it the program writes to the document.
