Question

Here’s the logic I’m trying to write, but I can’t find the proper Ruby way to say it:

if Object.id [occurs in this array ->] [13, 16, 234]
   #run this code if true
else
   #run this code if false
end

Basically I want to return true if an id occurs somewhere in a specific array.

Answer 1

I think you’re looking for Array#include?:

if [13, 16, 234].include? Object.id
    #run this code if true
else
    #run this code if false
end

Hope that helps!
