Is there anything wrong with this 'Do...While' code?

So... I'm just curious if anything is wrong with this code. My goal is to create a never ending loop until the users response is 'grayson'

here is my code so far:

var password = 'grayson';
var response;

do {
response = prompt('Who\s a sweet boy?');
  return response;
}
while (response !== password)
  document.write('welcome, brother.');

A "return" statement can only be used in a function, but I don't see a function here. If you remove that line, this code should do what you want.

Also, I'm guessing you meant to use that backslash to escape an apostrophe, but the apostrophe is missing.

What is the return statement used for? I'm not comprehending it's purpose.

Inside a function, the "return" statement causes the function to end, and optionally passes back a value to code which called the function. This will be covered in more detail as you progress in the courses.
