title: How to turn php time function into javascript function?
body: <p>I'm not that good at javascript (yet), so I need some help, with an alternative version of this php script (In javascript)</p>
  
  <pre><code>function until($format = ""){
      $now = strtotime("now");
      $nextTuesday = strtotime("-1 hour next tuesday");
      $until = $nextTuesday - $now;
      if(empty($format)){
          return $until;
      }else{
          return date("$format",$until);
      }
  }
  </code></pre>
  
  <p>Just need it to count down, until next tuesday, in a really short way (Not in 20+ lines, like all the other script I've seen)
  It should still return a timestamp, if it's possible (Need it for an offline app)</p>
  
  <p>So if anyone could help me, I would be really happy (Not that I'm not happy right now, but I would be even happier) :D</p>
