Sun 10 Jun 2012 03:34:48 AM UTC, original submission:  

ease.js (ironically, because of its OO nature) provides very little means to alter its internal functionality through hooks or plugins. This is intentional, to ensure that users to not write plugins that would make their code unportable to other systems without use of those plugins. It would cause inconsistencies and stifle adoption while providing very little befit other than a potential "cool" factor (who doesn't want a 'public selfdestructing foo' that would blow up the engine on use?).

However, certain events would be useful to watch for the purpose of analysis or enforcement of coding standards. For example, let's say a corporation wishes to disallow inheritance in favor of pure composition (which isn't a bad decision). If ease.js provided an event to be triggered on class creation, one could hook the event and throw an exception if the class is attempting to inherit from another.

  • The event will provide information but will not permit altering the internal data
  • As a consequence, classes cannot be modified through the use of hooks
  • This allows the creation of useful runtime analysis hooks without harming prospects of portability


Such hooks will be useful for runtime analysis, which may be necessary under certain circumstances due to the difficulties in statically analyzing JavaScript code.
