Dynamic path segments

We improved the code for our dice rolling web app by adding support for all possible combinations of number of dice and type.

We refactored the app.rb code with 1 addition and deleting 42 delitions!

#.rb

get("/dice/:number_of_dice/:how_many_sides") do

  @num_dice = params.fetch("number_of_dice").to_i

  @sides = params.fetch("how_many_sides").to_i

  @rolls = []

  @num_dice.times do
    die = rand(1..@sides)

    @rolls.push(die)
  end

  erb(:flexible)
end

.erb

<h1><%= @num_dice %>d<%= @sides %></h1>

<ul>
  <% @rolls.each do |a_roll| %>
    <li>
      <%= a_roll %>
    </li>
  <% end %>
</ul>
