Discussion on: Keyword Arguments of Ruby makes code more clear

[Edison Yap]

Didn't watch the video, but what I find interesting is that keyword arguments did not exist until Ruby 2.0, which means before Ruby 2.0, there's a totally different way to do hack it, and you'll sometimes see this in the wild :) (I've encountered this in Rails' DateTime library)

# Ruby 2.0
def method(first:, second:)
  puts "First: #{first}, Second: #{second}"
end

# Ruby 1.9
def method(options={})
  first = options.fetch(:first)
  second = options.fetch(:second)
  puts "First: #{first}, Second: #{second}"
end

Yes, it simplify code. Very useful.
