@spec get_indifferent(map(), atom()) :: term() | nil

Look up key in map using either the atom or string form, preferring the atom. Returns nil when neither key is present.

Convenient for code paths that consume both Elixir-native maps (atom keys) and JSON-decoded payloads (string keys) — e.g. webhook ingestion, pgflow job inputs, identify attrs.

Examples

iex> GoodAnalytics.Maps.get_indifferent(%{person_email: "a@b.com"}, :person_email)
"a@b.com"

iex> GoodAnalytics.Maps.get_indifferent(%{"person_email" => "a@b.com"}, :person_email)
"a@b.com"

iex> GoodAnalytics.Maps.get_indifferent(%{person_email: "atom-wins"}, :person_email)
"atom-wins"

iex> GoodAnalytics.Maps.get_indifferent(%{}, :missing)
nil
