skrollTop.js is a JavaScript smooth scrolling plugin that smoothly scrolls the page to a specific point within the document.

This library minimizes the code and still provides some great features like:

• Callback when done.
• You can optionally scroll to a different element of the window.
• Use different mitigations as jQuery UI has done in the past.
• Programmatically stop the animation.

How to make use of it:

Installation:

// With bower
bower install skrolltop

// With npm
npm install skrolltop

The primary use would be:

skrollTop.scrollTo({
    to: 800
});

Another example with all parameters would be as follows:

skrollTop.scrollTo({
    element: window,
    to: 800,
    easing: window.easings.easeOutBounce,
    duration: 600,
    callback: function() {
       console.log("finished!");
    }
});
