Functional Programming In a Nutshell
================================
### History
The idea of functional programming has been around since well-before the invention of computers.  The concepts of "partial application", "currying", and really higher level mathematics in-general lay out the framework used for the modern functional programming, more than its competing paradigms of imperative and Object-Oriented. 

###What is Functional Programming? 
In a nutshell, Functional programming is two things: 

 - Programming with the ideology that functions can be treated like a first-class-citizen
	 -  Think about math class:

Finding a derivative!
=====================
The definition of an derivative is as follows: 

$$
\lim_{\Delta x \to 0} { {f(x+\Delta x) - f(x)} \over \Delta x}
$$

Given that:

getUserObjectSomehow = () ->
    id: 5
    logged_in:true

do_something = (user) -> "> Logged in user #{user.id}:  #{JSON.stringify(user, null, 4)}" unless !user.logged_in
  
# Admittedly this is mildly dependent on underscore or lodash. 

log = console.log.bind(window)

A generalization for all even numbers is 
$$
2k
$$

where k is an integer. Therefore, a generalization for all odd numbers would be. 

$$
2k+1
