I called `prop` and passed in the parameters of `'selected'` and `true` but it is still not passing.

I called prop and passed in the parameters of 'selected' and true but it is still not passing. What's the deal?

js/app.js 
//Problem: It look gross in smaller browser widths and small devices
//Solution: To hide the text links and swap them out with a more appropriate navigation

//Create a select and append to #menu
var $select = $("<select></select>");
$("#menu").append($select);

//Cycle over menu links
$("#menu a").each(function(){
  var $anchor = $(this);
  //Create an option
  var $option = $("<option></option>");

  //Deal with selected options depending on current page
  if($anchor.parent().hasClass("selected")) {
    $option.prop("selected, true");
  }
  //option's value is the href
  $option.val($anchor.attr("href"));
  //option's text is the text of link
  $option.text($anchor.text());
  //append option to select
  $select.append($option);
});
//Create button 
var $button = $("<button>Go</button>");
$("#menu").append($button);
//Bind click to button
$button.click(function(){
  //Go to select's location
  window.location = $select.val();
});

Hi, its not passing because you have true inside your quote marks. It should be 

if($anchor.parent().hasClass("selected")) {
    $option.prop("selected", true);
}
