Passing hashes instead of method parameters [closed]

Ruby has implicit hash parameters, so you could also write

def my_method(options = {}) 

my_method(:width => 400, :height => 50, :show_border => false)

and with Ruby 1.9 and new hash syntax it can be

my_method( width: 400, height: 50, show_border: false )

When a function takes more than 3-4 parameters, it’s much easier to see which is what, without counting the respective positions.
