On: Is jQuery still relevant? (2014)

[whyileft]

I mean how often have you honestly seen something like this instead?

  (function(window, $) {
    var $some = $(.some-class-matching-one-element-in-a-tree-of-one-hundred-thousand');

    if ($some.length < 1) {
      return;
    }

    var $closest = $some.closest('.some-other-random-class');

    if ($closet.length < 1) {
      return;
    }

    var $window = $(window);

    $window.on('scroll.foo', $.throttle(function() {
      if ($some.offset().top > $window.scrollTop()) {
        $window.off('scroll.foo');
        $some.on('click.foo', function() {
          if ($closest.is('[chosen]')) {
            $closest.addClass('blue');
            $some.removeAttr('chosen');
          }
        });
      }
    }));
  }(window, jQuery));
