Classes - language feature

Example from JavaScript, TypeScript, Static Typescript:

class Person {}

class Person (object):
  def __init__(self, name):
    self.name = name

Example from Ruby:

# A tiny Person class in Ruby:
class Person
  attr_accessor :name, :age, :   # getter and setter methods
  def initialize(name, age)
    @name = name
    @age = age
  end
end

# Create a new Person object:
person = Person.new("John", 30)
puts person.name
puts person.age

# Change the age of the person:
person.age = 35
puts person.age
