Tiny

A JavaScript utility library oriented to real world tasks.

Purpose

Tiny aims to stay small and simple, while powerful and really useful.

Inspired by jQuery and Underscore, but using concepts from You might not need jQuery and the power of ES6 (ES2015).

Methods are implemented individually and not as part of a whole.

Installation

There are multiple ways to use Tiny.

Inline resource (recommended)

Grab the distributable code and embed into a <script> tag just before the closing </body> tag.

Module

Use NPM or Bower and include Tiny.js as a part of the build process.

npm install tiny.js

bower install tiny

From CDN

<script src="https://http2.mlstatic.com/ui/chico/tiny/[VERSION]/tiny.min.js"></script>
