1) thoughts about how to adopt the principles of aspect oriented programming to JavaScripts dynamic and functional nature.2) point (1) now gets accompanied by a working implementation - "modification.ao.js" - of an aspect oriented system as proof of concept.3) there is a working "logging" example now too as always if one needs to justify the exi…

roughly sketched

  • runtime based only and not using any kind of JavaScript "transpilers" or JavaScript build tools for "code weaving" as in e.g. AspectJ.
  • thus being forced focusing on what ES3 language core does provide.
  • implementation of prototypal method modifiers e.g. Function.prototype.before, Function.prototype.after, Function.prototype.around as minimal set of a kind of an AOP base that already supports library / framework agnostic modification of function based control flow by just wrapping additional behaviors / advice handlers around existing methods / functions.
  • clarify role of Joinpoint, Pointcut, Advice, Aspect; especially from this point of view of what makes them distinct from existing approaches in compiled and/or non dynamic and/or non functional programming languages.

Prevent function based "Role" pattern implementations[1] like "Mixin"s, "Trait"s or "Talent"s from getting instantiated by turning them into callable objects. Thus creating real objects but providing [call] and [apply] as standard call/delegation methods to them.
