Is there any better way to do this?

I was practicing some jQuery and I was wondering if there is an easiest or better way to do this because I feel the it's too repetitive

$("#navbar li").click(function(){
  var anchorID = $(this).children("a").attr("href");

  if (anchorID == "#home") {
    $(anchorID).removeClass("back").addClass("front");
    $("#about").removeClass("front").addClass("back");
    $("#contact").removeClass("front").addClass("back");
  } else if (anchorID == "#about") {
    $("#home").removeClass("front").addClass("back");
    $(anchorID).removeClass("back").addClass("front");
    $("#contact").removeClass("front").addClass("back");
  } else if (anchorID == "#contact") {
    $("#home").removeClass("front").addClass("back");
    $("#about").removeClass("front").addClass("back");
    $(anchorID).removeClass("back").addClass("front");
  }
});

Here is the codepen for a live version of it http://codepen.io/Jesusz0r/pen/LEJYBV

What about if you add a common class to all the sections in the HTML markup? I added one called section, then wrote this:

$("#navbar").on("click", "a", function(){
  var $this = $(this);
  var anchorID = $($this.attr("href"));
  var section = $('.section');

  section.removeClass("front").addClass("back");
  anchorID.removeClass("back").addClass("front");
});

I don't think I can pick 2 best answers right? I didn't know you can add multiple ids. Thanks!
