Yes - this is somewhat painful at present - and we do hope to make 
debugging web standalones in general less painful in time.

However, if you 'Test' your web standalone in a browser you can then 
open up the Developer Tools for the browser you are testing in - which 
gives you access to the JS console and all the other tools.

In JS you can use `console.log(...);` to have messages emitted to the JS 
console.

Additionally, I *think* you can use `debugger;` to have JS code break 
into the debugger in said browser's developer tools. I must confess I've 
not tried this myself (as our debugging is usually debugging the engine 
running in the browser, rather than debugging JS executed from the 
engine running the browser) - but I can't see why it wouldn't work.

Warmest Regards,

Mark.
