javascript

// e.g. roll(2).d(8) + roll().d(4) + 11
const roll = (n = 1) => ({
  d: (sides) =>
    Array.from({ length: n }, () => Math.ceil(Math.random() * sides)).reduce(
      (x, y) => x + y,
      0
    ),
})

ruby

class Integer
  # monkey patch for rolling virtual dice
  # e.g. 2.d8 + 1.d4 + 11
  def method_missing(name)
    if name[/^d\d+$/]
      n = name[1..-1].to_i
      self.times.map { rand(1..n) }.sum
    end
  end
end

python

from random import randrange
