Compared to other browsers the WebKit crew has released a JavaScript debugger quite soon after releasing their browser. And here it is Drosera named after the largest bug eating plant. Nice idea for a debugger name :-). And the screenshot is very promising.

After the element inspector this is the next really useful tool, Safari is becoming more and more useful for development. Even though JavaScript development using browsers is still a pain … but I am looking forward. The technology is just too promising to give up too soon.
Besides Firebug this will be another one of my tools that I stuff into my toolkit box.
