Node.js hack to inspect [Object object]
Raw
inspect-object-hack.md

Ever gotten some output on the console like [Object object], with no explanation? Can't find where it's being logged? Maybe it comes right before some ludicrous error or crash. Sometimes you just need a hack.

JavaScript

var ots = Object.prototype.toString;
Object.prototype.toString = function() { try { return JSON.stringify(this); } catch (e) { return ots.apply(this); } };

CoffeeScript

ots = Object::toString
Object::toString = -> try JSON.stringify @ catch then ots.apply @

This will let you actually see the contents of these mysterious [Object object]s.

Of course, this will screw up any libraries or code that relies on the default behaviour of Object.prototype.toString.
