We first need to create secret as an empty variable. The do component doesn't contain the condition, the while component does. So if the while condition is true(which is if the secret does not equal 'sesame'), then the do component runs.

var secret;

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

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

Hi, you used prompt method twice. Declare the variable secret outside the loop and the do..while loop syntax is like below:

do{
      // block of code
}while(condition)

Try this code:

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

Hope it helps!!!
