Person = Struct.new(:name, :age)

peeps = [
  Person.new("Jordan", 33),
  Person.new("Bob", 19),
  Person.new("Frank", 55)
]

Two steps, sort and access element

peeps.sort_by(&:age).first
=> #<struct Person name="Bob", age=19>

peeps.sort_by(&:age).last
=> #<struct Person name="Frank", age=55>

Avoid sort in one step

peeps.min_by(&:age)
=> #<struct Person name="Bob", age=19>

peeps.max_by(&:age)
=> #<struct Person name="Frank", age=55>
