I'd just like to go back and show 15-year-ago me Firebug or Chrome/Firefox's DevTools and inspector. It's pretty stunning how far the tooling has come and what you can do with it.
Heh, nearly that far back I was wishing I could install Venkman in IE.
JQuery and Firebug deserve a lot of credit for bringing some sanity to JS/web development. Sure things have moved on now, but they were ground breaking.
Man, it was 2006 (10 years ago!) when Firebug, Drosera [1] and Web Inspector [2] were all released. There were definitely a lot of people eager to have some tools to make front end web dev easier back then.
I never worked with Venkman but I recall all too well the hellish time I had debugging JS back around the turn of the millennium. IE was laughable, if there was an error in a script somewhere it would often just say error on line -1.
