I’ve been spending too much time with javascript lately. It probably isn’t healthy for me. I’ll get back to my own Clojure project and paying Ruby work soon enough, but right now I’m working on an interface-intensive project, so I’m up to my neck to explicit returns and key:value notation.
I was looking into improving my code (less coupling, more encapsulation, greater readability for me when I inevitably come back to extend it), and that led to some playing around with call, apply, and a prototype.js library method, Function#wrap, that puts this sort of casting and scope-alteration to use to enable metaprogramming. I sensed I was skirting the edge of a real revelation about how functional programming meets OOP in languages like javascript. But that’s for another post. Right now, I’d like to bite off more than I can chew on a different topic: how straightforward it appears to be to implement some RSpec-like Behavior-Driven Development specification-testing magic on javascript objects using Function#wrap.
