CountUp.js is a dependency-free, lightweight JavaScript "class" that can be used to quickly create animations that display numerical data in a more interesting way.
Current stars:
var options = {
useEasing : true,
useGrouping : true,
separator : ',',
decimal : '.',
prefix : '',
suffix : ''
};
var demo = new CountUp("myTargetElement", 0, 2560, 0, 2.5, options);
demo.start();
