=  is a match operator After an initial assignment it then becomes a match assertion. num = 1 To check the match assertion you can try this and it will be valid 1 = num Furthermore, these are also valid: [1] = [1] [num] = [num] Destructuring [score1, score2, score3] = [89, 93, 87] IO.puts score1  # 89 IO.puts score2  # 93 IO.puts score3  # 87 {:ok, value} = {:ok, 1000} IO.puts value # 1000 {:error, message} = {:error, "Uh oh"} IO.puts message # "Uh oh" Error when matching: {:foo, value} = {:bar, "nope"} ** (MatchError) no match of right hand side value: {:bar, "nope"} Matching function arguments Various function definitions and subsequent calls: def sum_two_nums(num1, num2) do num1 + num2 end sum_two_nums(2,5) def sum_two_nums(%{num1: num1, num2: num2}) do num1 + num2 end sum_two_nums(%{num1: 2, num2: 5}) def sum_two_nums([num1, num2]) do num1 + num2 end sum_two_nums([2,5]) There's so much more you ...

An anonymous function is composed of an optional parameter list, a body enclosed by fn -> and end . It returns a function definition and the potential for the function to be executed. Quite simply the anonymous function can be assigned to a variable which then can be subsequently called. Define an anonymous function:, greet = fn -> IO.puts "Hello World" end Of course that does nothing unless we call it! We can do that by using this dot notation - [function name].([optional parameters]) Like this: greet.() Where the output is: Hello World Anonymous functions with parameters add = fn(num1, num2) -> num1 + num2 end IO.puts add.(10, 15) IO.puts add.(12, 15) IO.puts add.(14, 19) subtract = fn num1, num2 -> num1 - num2 end IO.puts subtract.(15, 10) Output: 25 27 33 5 I hope these examples ignite an interest for you to further learn functional programming using Elixir.

Below is the PDF article I submitted to Software Developer's Journal  for their series they did on AngularJS. It was published in two of their issues: Nov. 15th 2013 -  AngularJS, Java and Drupal Tips & Tricks and Nov. 7th 2013 -  AngularJS Starter Kit . It's behind a paywall and thus hidden from most of the world. That sucks... which is why I'm posting my article here for all to see. Enjoy!

Engine Yard asked if my screencasts could be added to their listing. I said 'yes'! It's great to know that the screencasts I made several years ago can still help others learning Ruby today!

Presented at The East Bay Ruby Group on February 15th, 2011

This is my second talk related to Erlang. Both have been introductory and well received. I hope you enjoy my slide presentation. I also did a chat demo using real-time updates using Comet.
