Get the value of a key of each hash inside an array

I have got an array of hashes, for example:

[{"id" => "1", "name" => "Name 1"},
 {"id" => "2", "name" => "Name 2"}, 
 {"id" => "3", "name" => "Name 3"}]

I would like to get the value of the key "name" for each hash, similar to this:

["Name 1", "Name 2", "Name 3"]

I looked around for quite a while but couldn't find the answer I was looking for.

It's simplest to use Enumerable#map for this purpose:

array = [{"id" => "1", "name" => "Name 1"}, {"id" => "2", "name" => "Name 2"}, {"id" => "3", "name" => "Name 3"}]
array.map { |hash| hash['name'] }
# => ["Name 1", "Name 2", "Name 3"]
