It is written in JavaScript and after you’ve installed Everything, you can start getting familiar with the code.

6. App.js

built-in widgets for general use-cases.

7. RulersGuide.js

RulersGuides.js is a Javascript library which enables Photoshop-like rulers and guides interface on a web page. To create a guide, click the vertical or horizontal ruler and drag-n-drop it somewhere outside the ruler. It is possible to open/save created guides as grids using corresponding hotkeys. Rulers can be locked, so that one of the rulers will scroll along the page and the other will be always visible. Guides can be snapped to defined number of pixels. Detailed info mode is available, which shows position and size of regions created by the guides.

8. Draggabilly

Draggabilly is a small (~10k) JavaScript library that does one thing well — make that shiz draggable. It makes it super easy to add drag-and-drop functionality to your site.

13. Steady.js

Steady.js is a jank-free module to do logic on the onscroll event without performance regressions in @media-query like conditions. First, Steady attaches a handler to the onscroll event, that excutes the trackers. Then it calls another function that checks the conditions with values inside a requestAnimationFrame to avoid making the onscroll handler fat and slow, which will jank our scrolling.

14. MotorCortex.js

MotorCortex makes web animations easy, providing the ability to describe them through CSS-like syntax and stop messing animation logic with your actual javascript code.

15. Beeplay.js

Beeplay.js lets you write a song in JavaScript.
