What is the fastest way to find an element in an array using ruby?

Question

ruby

There is an array like

arr = [
{key: 1, value: some_value441},
{key: 2, value: some_value212},
{key: 3, value: some_value33},
{key: 4, value: some_value44},
]

It is necessary to find the value of value by the key value, and the algorithm should be the most optimal, who can tell in which direction to move?

Answer 1

Array#find
Array#detect

items = [
  { name: :sergey, value: :qa },
  { name: :boris, value: :c_plus_plus_dev },
  { name: :vlad, value: :analytic },
  { name: :eugene, value: :marketer }
].detect { |item| item[:name] == :boris }[:value]
