Ruby does string equal one of the strings in an array of strings?

Question

Is there an easy way to sort of call something similar to the database In query?

Does "mystring" exist in ["string1","mystring","string2"] => would return true

Does "mystring" exist in ["string1","string2","string3"] => would return false

Answer 1

["string1","mystring","string2"].include? "mystring"

See: Enumerable#include?
