Do while?

This is the code we used in the last code challenge. After learning about do...while loops, don't you think this would work better in the do...while style? Re-write the code to use a do...while loop.

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

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

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

script.js

It looks like you just quoted the challenge here, but have not written any code. Did you mean to ask a question about it?

Perhaps a few hints will get you started:

  • in a "do...while", the "while" part (with the test) comes after the code block
  • this guarantees the code block will always run at least once
  • you won't need to ask the question in two places anymore
  • you will still declare the variable at the top, but you no longer need to set it there

I entered this as my answer but I keep get it wrong. What am I doing wrong?

CODE

do {
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.");

Never post a new question as an "answer" to another question! Start a fresh new one instead.

In the meantime, take a look at the hints given to bhupendra, it seems you have similar issues.
