5. scrollReveal.js

ScrollReveal.js in a simple way is for you  to create and maintain how elements fade in, triggered when they enter the viewport. By adding a data-scrollreveal attribute to an element, it will automatically be revealed (using default values) as soon as the element is within the viewport. However, scrollReveal.js allows you to define custom reveals, using descriptive language.

6. Countable.js

Countable.js is a JavaScript function to add live paragraph-, word- and character-counting to an HTML element.

8. Gander

Gander, in its most basic form, wraps itself around functions to provide execution times. Times are provided in sub-milliseconds when the precision is available (process.hrtime, performance.now) and milliseconds when not. Generally, though, gander exposes callbacks that are invoked before and after a function is called so that you can perform thorough investigations and/or mad science.

Gander supports CommonJS/node.js and AMD/require.js imports. You can also use it in your web app via a normal script tag and it will add itself to the window object.

9. Hammer.js

Hammer.js makes it simple to add touch gestures to your website, recognising touch gestures as well as mouse gestures and pointerEvents. It even has support for multiple instances at the same time, so you can create multi-user touch interfaces.

10. Boba.js

Boba.js is a small, easily extensible JavaScript library that makes working with Google Analytics easier, as Boba supports the old ga.js library but also works with the new analytics.js library. It has one out of the box function, trackLinks, and makes tracking everything else child’s play.

11. Select or Die

Select-or-Die is a jQuery plugin to style select elements. If you feel like adding a placeholder that’s displayed before anything is selected. Once a selection has been made the placeholder will be removed until the user clicks the SoD again. You can also add a prefix that’s displayed in front of the selected option.

When enabled “Keyboard Cycle”, it allows the user to cycle the list using his/hers arrow keys. Lets say an option have been added to the native <select>, then you might want to update the SoD to reflect the native <select>. Then it’s just a matter of running the update method and the SoD will update with the new option.

12. Flickerplate

Flickerplate is a cool jQuery plugin that lets you flick through content. This plugin is by definition a jQuery plugin and so is required. It also requires Modernizr for touch detection and the jQuery.Finger library for touch events. Both jQuery and a custom build of Modernizr are supplied.
