I just finished reading OOP The Good Parts: Message Passing, Duck
Typing, Object Composition, and not
Inheritance by Nick Fitzgerald.
Obvious references to Douglas Crockford's
aside, the article builds on some interesting points by authors like
Raganwald that will resonate with many DailyJS readers:
What if code re-use has nothing to do with inheritance, but uses composition, delegation, even old-fashioned helper objects or any technique the programmer deems fit?
Fitzgerald defines a method called
quacksLike that he uses
to formalize object capability detection and
for object composition.
These ideas aren't new, but there's an interesting code example of a DOM
library that uses these methods. It'll be particularly interesting to
fans of Let's Make a Framework.
Despite functools follows CommonJS specs, my actual aim is to improve the experience of DOM programming
It supports features like iterators, functional composition, currying,
and partial function application.
