five-plus

A library to overcomplicate 5. Better.

Idiomatic CoffeeScript rewrite of the legendary five.js by @jackdcrawford.

Usage

Require the module

Five = require 'five-plus'

In the browser

<script type="text/javascript" src="./lib/five.js"></script>

Basic 5

Five()                  # 5

Addition

Five() + Five()         # 10

Multiplication

Five() * Five()         # 25

# Note: a more idiomatic way to do this in CoffeeScript
Five() ** 2             # 25

Division

Five() / Five()         # 1

Different sorts of 5

five = new Five()

five.upHigh()           # ⁵
five.downLow()          # ₅
five.tooSlow()          # 5, with a ~500 millisecond delay
five.roman()            # V
five.morseCode()        # di-di-di-di-dit

Development

The code

All of the logic & heavy lifting is achieved in one self-contained file:

./lib/five.js

Compiling

Compilation is done using cake under the hood with an npm-prepublish script:

npm install

Tests

npm test
