So prefix this with `javascript:` and compress it to one line and it works a treat. I've been playing with it in the chrome inspetor to get started

class Lasagna
  EXPECTED_MINUTES_IN_OVEN = 40
  PREPERATION_MINUTES_PER_LAYER = 2

  def remaining_minutes_in_oven(actual_minutes_in_oven)
    expected_minutes_in_oven - actual_minutes_in_oven
  end

  def preperation_time_in_minutes(number_of_layers)
    number_of_layers * PREPERATION_MINUTES_PER_LAYER

# A simple function to return a signed, expiring url for Amazon Cloudfront. 
# As it's relatively difficult to figure out exactly what is required, I've posted my working code here.

# This will require openssl, digest/sha1, base64 and maybe other libraries. 
# In my rails app, all of these are already loaded so I'm not sure of the exact dependencies.

module CloudFront
  def get_signed_expiring_url(path, expires_in, private_key_filename, key_pair_id)

    # AWS works on UTC, so make sure you are not using local time

// Problem: This doesn't work
// true || throw new Error('some_var not defined')
// > Uncaught SyntaxError: Unexpected token throw

// I would approach this by creating another function, either for 
// after the ||, or to wrap the whole thing. It's not exactly ideal
// but it feels idiomatic in a functional language.

//--
// Suggestion 1: Define a wrapper function for throw
