Ruby Array find_first object?

Question

Am I missing something in the Array documentation? I have an array which contains up to one object satisfying a certain criterion. I\'d like to efficiently find that objec

Answer 1

Do you need the object itself or do you just need to know if there is an object that satisfies. If the former then yes: use find:

found_object = my_array.find { |e| e.satisfies_condition? }

otherwise you can use any?

found_it = my_array.any?  { |e| e.satisfies_condition? }

The latter will bail with "true" when it finds one that satisfies the condition. The former will do the same, but return the object.
