Because it’s come up a few times on the Elixir slack I figured I should write down a short post on a simple pattern (or two, I guess) for how to handle health checks in a convenient way while avoiding spamming logs.

10 Common Code Refactoring | Elixir
This article comprises of common Elixir coding techniques that you may or may not know.
A Jist of the Article
We usually encounter a situation like we expect a map has certain key and if not we need to send some default value.
Immediately, we will end up using Map.has_key? like in the following way
currency =
if(Map.has_key? price, "currency") do
price["currency"]
else
"USD"
If you see any such lines in your code then it is time to refactor them as
currency = Map.get(price, "currency", "USD")
However, you can also take this to the next level like
currency = price["currency"] || "USD"

Except these will not work in the same way when price = %{"currency" => nil}, and this is an important difference.

Enum.map(pickup, fn
{"latitude", lat} -> {"lat", lat}
{"longitude", long} -> {"long", long}
{"pickupId", pickup_id} -> {"pickup_id", pickup_id}
{"stopName", stop_name} -> {"stop_name", stop_name}
{"zip", zip} -> {"zipcode", zip}
anything -> anything
end)
|> Enum.into(%{})
Every time someone does Enum.map(map, function) |> Enum.into(%{}) Map.new/2 cries.

Of course you are right. I just considered no-key and key with value as nil are both same. I will update like you said.
Anyway, Good Catch
