Using alert() for debugging javascript is a pain. Firebug makes it a lot easier and enables several debug facilities (e.g inserting breakpoints, stepping into methods, adding variable watches) but a painless logging mechanism would still be very useful to supplement Firebug’s features.

Enter Blackbird, a simple javascript logging tool which has a very clean, nice API and a cool console. It’s really worth to check out, you can download the Blackbird files here and my demo here to try out its features. (If you use my demo, you have to save the Blackbird files in a directory named blackbirdjs that is situated in the same directory as the demo page)

Blackbird’s motto says it all: say “hello” to Blackbird and “goodbye” to alert().
