That isn't real. It wouldn't pass peer review. Here is the actual code:

function GetCookieValue(x) {
  return JSON.stringify(x);
}

user.cookies.agreed = Boolean(GetCookieValue(true));

if(!DarkPatternPopup()) {
  // Make sure we respect the user choice
  user.cookies.agreed = Boolean(GetCookieValue(false));
}

if(user.cookies.agreed) CollectData(user);
