TIP: Javascript debugger

  
Have you ever suffered from the lack of debugging capabilities in javascript? Well, those days are over. Just install FireBug for Firefox and you will have:
  • DOM inspector
  • Step-over, step-into, break on error for any script
  • call stack and variable inspection
  • XMLHttpRequest logs

And the user Interface is very good.
Firebug 1.0 Beta was released. Checkout the new features at: http://www.getfirebug.com/index.html

There's also a version of Firebug for other browsers, like IE and Safari. Get it at: http://www.getfirebug.com/lite.html

Happy debugging,
Rodrigo
Another interesting Firefox extension that's more dedicated to Javascript and less to the remaining aspects (like the DOM model, etc) but which allows interactive debugging and javascript command evaluation on the fly, is the JavaScript Debugger extension (aka Venkman) available at https://addons.mozilla.org/firefox/216/
