Countdown module that hides an element when a specified date is reached I have the following piece of code which hides an element when a specified date was reached. I would like to get some tips about do's and don'ts.

Specifically, I'm interested in:


improvements brought to this code
avoid bad practices


And whatever you guys consider I should be careful about.

var Timer = (function(){
    var $el = $('#element');

    function count() {
        setInterval(function() {
            check();
        }, 1000);
    }

    function hide() {
        $el.hide();
    }

    function check() {
        var currentDate = new Date();
        var endingDate = new Date("July 25, 2016 11:06:00");

        if (currentDate.getTime() &gt;= endingDate.getTime()) { 
            hide();
        }
    }


    return {
        count: count  
    };
})();

Timer.count();
My notes:


There is no need to create a function that calls check, you can just pass check
There is no need for function hide, you only call it once, and it only has 1 line of code, I would inline that function
Very minor, but there is no need to declare endingDate inside check, I would declare it once outside of the function
You are using a revealing pattern, I would use a simple self executing pattern. On the whole if you expose 1 function that you will run only once, use a self executing function.
Once the date is passed you will be hiding that element non-stop every second, that sounds like overkill
I abhor anonymous functions, choose a meaningful name, and you can spare a line of comment ;)


My approach with these notes would be

    (function HideElementWhenTimeComes (){
      var $el = $('#element'),
          endingDate = new Date("July 25, 2016 11:06:00"),
          intervalID;

      function check() {
        var currentDate = new Date();
            if (currentDate.getTime() &gt;= endingDate.getTime()) { 
              $el.hide();
              clearInterval(intervalID);
            }
      }

      intervalID = setInterval(check , 1000 );

    })();
