A front-end JavaScript library for user-interface developers.

Chicago.js is a small, fast JavaScript library built specifically with front-end and user-experience developers in mind. Primarily, the library is a collection of useful utility and cross-browser support functions, allowing for quicker and easier development it fewer bugs and cross-browser/device issues.
Given that there are already a ton of JS libraries out there, I’ve created several goals for this project:

To be fast, lightweight, and easily deployable
To create and allow for a consistent cross-browser/device experience
To find real solutions for real problems – to not be repetitive
To be modular and extendable – creating a plugin for the library should be easy
To always be reliable through rigorous testing
To allow for easy contribution in the spirit of open-source software

Note: Chicago.js is, for the time being, dependent on jQuery. Make sure to reference jQuery before you include Chicago.js in your project.

Chicago.js can be installed several different ways:

Download the latest release from GitHub
Unzip the package
Copy dist/Chicago.js or dist/Chicago.min.js from the package into your project’s folder
Reference the file in the footer of your HTML pages:

Using Bower
cd ~/your/project
bower install Chicago
Using NPM
cd ~/your/project
npm install chicago

How to use Chicago.js
Chicago.js creates an object on the window/global called Chicago. You can access this object and it’s methods/properties by referencing the global object directly:
var myChicago = window.Chicago;
The recommended way to access the global Chicago object is by passing it as an argument of an anonymous closure:
;(function(_c) {

// Now we can use _c to access Chicago…
console.log( _c.version ); // will output 1.0.0
