#Cash An absurdly small jQuery alternative for modern browsers (IE9+)

Cash is a small library for modern browsers (Chrome, Firefox, Safari and Internet Explorer 9+) that provides jQuery style syntax for manipulating the DOM. Utilizing modern browser features to minimize the codebase, developers can use the familiar chainable methods at a fraction of the file size. 100% feature parity with jQuery isn't a goal, but cash comes helpfully close, covering most day to day use cases.

Usage

Add cash to your project on your server or using the jsDelivr or CloudFlare CDNs, and use cash to manipulate the DOM!

<script src="https://cdn.jsdelivr.net/npm/cash-dom@1.3.5/dist/cash.min.js"></script>
<script>
$(function(){

  $('html').addClass('dom-loaded');

  $('<footer>Appended with cash</footer>').appendTo(document.body);

});
</script>

Cash is also available through NPM as the cash-dom package:

npm install cash-dom --save-dev

And through Bower as cash:

bower install cash

Documentation

$()

This is the main selector method for cash. It returns an actionable collection of nodes. If a function is provided, the function will be run once the DOM is ready.

$(selector,[context]) // => collection
$(node) // => collection
$(nodeList) // => collection
$(htmlString) // => collection
$(collection) // => self
$(function) // => document ready callback

Collection Methods

These methods from the collection prototype ( $.fn ) are available once you create a collection with $() and are called like so:

$(element).addClass(className) // => collection

Attributes	Collection	CSS	Data	Dimensions	Events
$.fn.addClass()	$.fn	$.fn.css()	$.fn.data()	$.fn.height()	$.fn.off()
