Projects in the repo

cards: Introductory project to elixir developed while taking the Udemy course "The complete Elixir and Phoenix bootcamp and tutorial" by Stephen Grider.

Creates a new keyword list and access a property

iex> colors = [{:primary, "red"}, {:secondary, "blue"}]
iex> colors[:secondary]
"blue"

Creating a map and accessing its values directly

iex> colors = %{ primary: "red", secondary: "blue" }
iex> colors.secondary 
"blue"

Using pattern matching with a map

iex> colors = %{ primary: "red", secondary: "blue" }
iex> %{secondary: secondary_color} = colors
iex> secondary_color
"blue"

Update a value in a map using a function of the Map type

iex> colors = %{ primary: "red", secondary: "blue" }
iex> Map.put(colors, :primary, "yellow")
%{primary: "yellow", secondary: "blue"}

Update a value in a map using the pipe | symbol

iex> colors = %{ primary: "red", secondary: "blue" }
iex> %{ colors | primary: "yellow" }
%{primary: "yellow", secondary: "blue"}

Put a new value to an existing map

iex> colors = %{ primary: "red" }
iex> Map.put_new(colors, :secondary, "blue")
%{primary: "red", secondary: "blue"}
