Step 1. Install the Wine Team Ubuntu PPA

First start by installing Wine btw it's a utility to install windows apps in linux :

open the Terminal and :

   sudo add-apt-repository ppa:ubuntu-wine/ppa     
   sudo apt-get update && sudo apt-get upgrade
   sudo apt-get install wine1.7 winetricks

def fib(n)
  return n if 1 >= n
  fib(n-1) + fib(n-2) if n > 1
end

def fib_include(n)
  return n if (0..1).include? n
  fib_include(n-1) + fib_include(n-2) if n > 1
end

var resultado = soma(1, 2);
expect(resultado).to.equal(3);

dayvsonlima

function soma(a, b){
  return a + b;
}
