# elixir provides a way to fetch from and update nested maps
# lets say you have a map:

greetings = %{morning: %{friend: "sup", coworker: "hey"}, afternoon: %{friend: "sup", coworker: "good afternoon"}}

# there is a built in (erlang) Kernel function `get_in`
get_in(greetings, [:morning, :coworker]) #=> "hey"

# to updated a nested map use `put_in`
new_greetings = put_in(greetings, [:afternoon, :friend], "yo there") # => %{afternoon: %{coworker: "good afternoon", friend: "yo there"}, morning: %{coworker: "hey", friend: "sup"}}

Pimp my site

Intro

JETHRO: Hello, my name is Jethro Wilkins and you're on pimp my site.

JETHRO: Craig came in today looking for some help with his blog. Craig loves his cat but his blog could really use some help. It looks dull, uninteresting and boring to look at. Looks like something his grandma would blog about. So he came in here looking for some help.

CRAIG: Everyone says they like the pictures of my cat, but they can't stand be on the site for more than 2 minutes. I don't know, maybe it's the gray background or something...but bottom line is I need these guys to really help me out.
