Episode 5: A Walled Off Garden of Perfection

Can’t change your variables once you assign a value? WTF? Surely, this is something up with which we cannot put! Or: a round-about introduction to some of the concerns addressed by the functional programming paradigm.

In This Episode:

• “I’ve been thinking about Object Oriented Programming.”
• “And you survived.”
• Concurrency and shared state
• Changing the value of 2
• What if we can’t change a variable’s value?
• Side effects: minus the sides. And the effects.
• A functional primer and the unit test
• No side effects? No dependency injection!
• Does dependency injection break the “encapsulation” contract?
• Lock the doors so we can invent windows.
• Mock object makes a mockery of … well ….
• Separating values from behavior
• The inversion of the inversion
• Apparently, we’re really interested in address books.
• What about side-effects, though? I mean, right?
• Separating side-effects from calculations
• A walled-off garden of perfection
• Don’t mock me
• Recursion
• When copying is not copying
• What’s the difference between antidote and poison?
• Mocking and Dependency Injection, a heretical view
• Rich Hickey, Simon Peyton Jones, Martin Ordesky
• Clojure: What if I only use blue?
• Scala: What if we add blue, and every other color, too?
• After all this, why OO ever?
• Simple Made Easy
