    copied!<p>I'm working on a project that will feature many of these 'second by second' timers that will display how many animals are born per second :) Do you have any suggestions as to how I could best optimize this script for performance and DRY-ish?</p> <p>JSFiddle here - <a href="http://jsfiddle.net/gJy4x/32/" rel="nofollow">http://jsfiddle.net/gJy4x/32/</a> </p> <pre><code>var start = new Date(), midnight = new Date(start.getFullYear(), start.getMonth(), start.getDate(), 0), first = new Date(start.getFullYear(), start.getMonth(), 1); setInterval(function () { var now = new Date(), secondsFromStart = Math.floor((now - start)/1000), secondsFromMidnight = Math.floor((now - midnight)/1000), secondsFromFirst = Math.floor((now - first)/1000), puppiesBornPerSec = 3.16, puppiesStart = Math.round(secondsFromStart*puppiesBornPerSec*100) / 100, puppiesMidnight = Math.round(secondsFromMidnight*puppiesBornPerSec*100) / 100, puppiesFirst = Math.round(secondsFromFirst*puppiesBornPerSec*100) / 100; // 3 puppies born every second $('#badge01').text(puppiesStart.toFixed(2)); $('#s01 .morning').text(puppiesMidnight.toFixed(2)); $('#s01 .month').text(puppiesFirst.toFixed(2)); // 5 kittens born every second $('#badge02').text(Math.floor(secondsFromStart*5)); $('#s02 .morning').text(Math.floor(secondsFromMidnight*5)); $('#s02 .month').text(Math.floor(secondsFromFirst*5)); // 7 rats born every second $('#badge03').text(Math.floor(secondsFromStart*7)); $('#s03 .morning').text(Math.floor(secondsFromMidnight*7)); $('#s03 .month').text(Math.floor(secondsFromFirst*7)); }, 1000); </code></pre>
