Does Ruby make a string equal to one of the strings in an array of strings?

Question

Is there an easy way to sort a call with something similar to a database In query?

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

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

Answer 1

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

See: Enumerable # include?
