Keyword.get

You're seeing just the function get, go back to Keyword module for more information.

get(keywords, key, default \\ nil)

get(t(), key(), value()) :: value()

Gets the value for a specific key.

If key does not exist, return the default value (nil if no default value).

If duplicated entries exist, the first one is returned. Use get_values/2 to retrieve all entries.

iex> Keyword.get([], :a)
nil
iex> Keyword.get([a: 1], :a)
1
iex> Keyword.get([a: 1], :b)
nil
iex> Keyword.get([a: 1], :b, 3)
3

With duplicated keys:

iex> Keyword.get([a: 1, a: 2], :a, 3)
1
iex> Keyword.get([a: 1, a: 2], :b, 3)
