aske about code

$("#menu a").each(function(){
  var $anchor = $(this);

var $button = $("<button>Go</button>");
$("#menu").append($button);
//Bind click to button
$button.click(function(){
  //Go to select's location
  window.location = $select.val();
});

//Modify CSS to hide links on small width and show button and select
  //Also hides select and button on larger width and show's links
//Deal with selected options depending on current page

i wont to ask to this code do

window.location = $select.val();

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>");

  //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();
});

//Modify CSS to hide links on small width and show button and select
  //Also hides select and button on larger width and show's links
//Deal with selected options depending on current page

Assigning a value to window.location effectively navigates the browser to the new location. It is the same as if you had typed the new location into the browser navigation bar. For more information and examples see window.location documentation .

The code window.location = $select.val(); takes the current value of the select, which is the value of the selected option. The value of the selected option holds the URL based on the href values in the menu.

Assigning this href to window.location is the same as navigating to the new href.
