why do we need to make 'selected' as true?
$option.prop('selected', true);
//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();
});

You set the "selected" property here to complete the challenge.
But the practical reason for doing so is that the option with the "selected" property is the one that will be initially displayed in the select box. This causes the select box to show the same choice as the currently active tab.
You can see it work if you select the "preview" button in the challenge and then reduce your window size so that the select box becomes visible.

3,182 PointsThank you for your reply Steve. There are two parts i have to confirm with you.
When a value is assigned to var $option = $("<option></option>"); "selected" as a property is assigned to option at the same time as below?
<select> <option selected> </option> </select>
I did not get the part when you say "reduce your window size so that the select box becomes visible. "

And the reason I said you might need to reduce the window size is because the select box is only shown on very narrow screens. Otherwise, it is hidden by the media queries and the tabs are displayed instead.
