Hi John,

I don't think there is anything wrong with passing the javascript as a string. 
In fact, for your example, this is what I would prefer.

I see the JS api as a very convenient way to script dynamically generated javascript together. Things like:

(JSStream on: 'somecondition') 
	then: (html jQuery ajax callback: [ ...executed ST callback when JS someCondition is true ...]
	else: (html jQuery ajax callback: [ ... executed ST callback when JS someCondition is true ...]

But for anything that can be statically specified, my preference goes to either external java scripts files or simply using literal strings and the JSStream.

best regards,
