I've this script that make change a class every 3 seconds. How do I stop the loop, so it will stop on the second class?

$(function() {

  var $target = $("#wrap");

  var classes = ['hide', 'show'];

  var current = 0;

  setInterval(function() {

    $target.removeClass(classes[current]);

    current = (current+1)%classes.length;

    $target.addClass(classes[current]);

  }, 3000); // 1500 ms loop

});
