Using Marshal for Serialization

The Marshal provides a way to serialize Ruby objects into a binary format and then deserialize them back to Ruby objects.

Execution:

person = { name: "Alice", age: 30 }
#=> {:name=>"Alice", :age=>30}
serialized_person = Marshal.dump(person)
#=> "\x04\b{\a:\tnameI\"\nAlice\x06:\x06ET:\bagei#"

File.open('person.dat', 'wb') do |file|
  file.write(serialized_person)
end
#=> 30
