Factorial in Coffee Script

A sample function to calc the factorial of a number. It has only a number as parameter.

Compiling

It uses Grunt with convenient methods for compiling the code, running tests, and more. To use it, install the required dependencies as directed and then run some Grunt commands.

Install Grunt

From the command line:

1. Install grunt-cli globally with npm install -g grunt-cli.
2. Install the necessary local dependencies via npm install

When completed, you'll be able to run the various Grunt commands provided from the command line.

Unfamiliar with npm? Don't have node installed? That's a-okay. npm stands for node packaged modules and is a way to manage development dependencies through node.js. Download and install node.js before proceeding.

Available Grunt commands

Build - grunt

Run grunt to run tests locally and compile the coffee script files.

Tests - npm test

Runs Jasmine tests headlessly in PhantomJS (used for CI).

Watch - grunt watch

This is a convenience method for watching coffee script files and automatically building them whenever you save.

Troubleshooting dependencies

Should you encounter problems with installing dependencies or running Grunt commands, uninstall all previous dependency versions (global and local). Then, rerun npm install.
