Folks, maybe that was reasonable in, oh, 2002 or so, but here in 2011 if you're using a desktop browser there's just no excuse for not using a proper debugger to set breakpoints, walk through code, inspect variables, inspect the structure of the DOM, etc., etc. No excuse at all. None! Pas d'excuse! ¡No excusa! Keine Entschuldigung! Nessuna scusa!
- IE8 & IE9: Semi-reasonable debugger and tools built in, or use the free version of VS.Net
- IE6 & IE7: Use the free version of VS.Net (or the old standalone script debugger)
- Firefox: Get the excellent, and free, Firebug plug-in
- Chrome: Has a good debugger and tools built in
- Safari: Has a good debugger and tools built in (you may have to enable the menu item in the options)
- Opera: Has a good debugger and tools built in
