Finding the higher version between two objects

higher_version.rb

objects = [
  # This is the higher version
  { name: "thing1", version: "5.15.6" },
  # but string comparison would think this one is
  { name: "thing2", version: "5.6.1" },
]

objects.sort do |a, b|
  # The comparison operator works as you'd expect on arrays of numbers
  a_comps = a[:version].split(".").map(&:to_i)
  b_comps = b[:version].split(".").map(&:to_i)
  a_comps <=> b_comps
end.last
