Javascript setInterval代码的优化建议，该代码显示每秒出生的小狗、小猫等数量

我正在做一个项目，其中有许多“逐秒”计时器，可以显示每秒出生的动物数量：）你对我如何优化这个脚本以提高性能和效率有什么建议吗

我在这儿闲逛-

数据中省略整数小数的解决方案如下所示
在本例中，您需要添加一个类“s”和数据量

<section class="s" data-quantity="3.16" id="s01">
    <h1>if 3.16 puppies are born every second</h1>
    <b id="badge01" class="now">0</b> puppies have been born so far.<br>
    <b class="morning">?</b> puppies have been born today<br>
    <b class="month">?</b> puppies have been born since the first of this month.
</section>
<hr>
<section class="s" data-quantity="5" id="s02">
    <h1>if 5 kittens are born every second</h1>
    <b id="badge02" class="now">0</b> kittens have been born so far.<br>
    <b class="morning">?</b> kittens have been born today<br>
    <b class="month">?</b> kittens have been born since the first of this month.
</section>
<hr>
<section class="s" data-quantity="7" id="s03">
    <h1>if 7 rats are born every second</h1>
    <b id="badge03" class="now">0</b> rats have been born so far.<br>
    <b class="morning">?</b> rats have been born today<br>
    <b class="month">?</b> rats have been born since the first of this month.
</section>

除了Abraham的脚本，为了实现最佳优化，如果可能的话，应该缓存循环中的所有内容。例如

$（“.s”）

，

.children（'.now'）

被多次执行

//cache them
var elems = [];
$(".s").each(function(){
   var $this = $(this);
   elems.push({
      obj: $this,
      data: $this.data('persec'),
      now: $this.children('.now'),
      morning: $this.children('.morning'),
      month: $this.children('.month'),
   });
});

你可以尝试使用数据，每个都像这样@AbrahamUribe-漂亮！对于没有小数的量，有没有办法省略小数？@AbrahamUribe-非常感谢你的帮助。有没有办法在10亿或10亿马克处添加逗号？你可以尝试使用类似“伟大”的东西！还有一个问题，你将如何整合@thanh关于如何缓存循环中的所有内容的建议？哇！这太棒了。谢谢@Abraham！

midnight = new Date(start.getFullYear(), start.getMonth(), start.getDate(), 0),
