CoffeeScript upcoming changes.

CoffeeScript 1.7 is shaping up to be a pretty kick-ass release with significant improvements. Here are the ones I'm most excited about, in order of my own excitement.

Notes From "Practical Object-Oriented Design In Ruby" by Sandi Metz

Chapter 1 - Object Oriented Design

The purpose of design is to allow you to do design later, and it's primary goal is to reduce the cost of change.

SOLID Design:

  • Single Responsibility Principle: a class should have only a single responsibility
  • Open-Closed Principle: Software entities should be open for extension, but closed for modification (inherit instead of modifying existing classes).
  • Liskov Substitution: Objects in a program should be replaceable with instances of their subtypes without altering the correctness of that program.
  • Interface Segregation: Many client-specific interfaces are better than one general-purpose interface.
require 'active_support/core_ext/time'
class BusinessHoursFeature
# This feature is only available between the hours of 10am and 4pm
def enabled?
Time.use_zone('Pacific Time (US & Canada)') do
now = Time.zone.now
am, pm = Time.zone.parse('10:00'), Time.zone.parse('16:00')
weekday = !(now.saturday? || now.sunday?)
