Introspection: A look inside

Recently I have been creating a small utility framework. Written in JavaScript its purpose is to fill in a couple of holes and short falls of JavaScript. With these changes I have decided to re-implement an introspection method/function. The goal or purpose is to have a console that can quickly output properties, methods or otherwise inner workings of an object.

This is an early release. Polishing and fixes are required but the basis is there. The intent is to use this as a debugging tool. I know there are alternatives in existence.

  • Firebug
  • Google-Chrome console
  • Opera console
  • IE 8 now has a console
  • Firebug lite

I was planning on having a light weight tool that is standardized across browsers and platforms that is completely customizable. This article will change in the near future.
