But for a single statement no need to wrap the line within curly braces because, for any iteration/loop if the condition satisfy then by default first line of code will be executed. This statement is also true for other programming languages. Keep in mind two things when you want to write a loop statement: 1. Statements that you need to iterate 2. Termination or exit from loop

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.
