Helping to understand the `this` variable in JavaScript
Product Details

The issue with all of this is that the CouchDB callback is asynchronous, and "this.bar" is now within the scope of the callback function, not the class. Does anyone have any ideas for accomplishing what I want to? I would prefer not to have a handler object that has to make the db calls for the objects, but right now I am really stumped with the issue of it being asynchronous.
