After migrating from heroku to dokku, we had to also chance codeship so we deploy to dokku. I followed the following steps to successfully deploy to dokku.

Save the public key of the codeship project. It is found in Project Settings > General Settings.
Copy the public key to a file /tmp/codeship_projectname.pub.
Make sure when pasting, all the contents are in a single line and not multiple lines.
Add the public key to dokku using the following command in console. Reference.

cat /tmp/codeship_projectname.pub | ssh root@yourdokkuinstance "sudo sshcommand acl-add dokku [description]"

Key difference between OOP and FP in JavaScript

In OOP we have mixed instance data and class functions:

class Animal { 
  constructor(name) {
    this.name = name;
  }
 speak() {

	var Router = require('director').Router;
	var Dispatcher = require('flux2/dispatcher');
	var React = require('react');
	var Content = require('./components/content');
	var routes = require('./routes');

	React.render(
	React.createElement(Content, null),
	document.getElementById('content')
	);

	function offset(count, offset, limit) {
	const finalOffset = Math.max(Math.min(count, offset), 0);
	const remainedCount = Math.min(count, count - finalOffset);
	const finalCount = (typeof limit === 'number') ? Math.min(limit, remainedCount) : remainedCount;
	return { offset: finalOffset, finalCount: finalCount };
	}

	console.log(offset(10, 0)); // {"offset":0,"finalCount":10}
	console.log(offset(10, 4)); // {"offset":4,"finalCount":6}
	console.log(offset(10, 10)); // {"offset":10,"finalCount":0}
