Debugging javascript is the most painful part of web development. So I decided to search for some good tools to debug javascript issues. Here is what I found
The Microsoft Script Debugger is a debugging environment that extends any Microsoft ActiveX® Scripting host application?for example, Microsoft Internet Explorer (IE) or Microsoft Internet Information Server (IIS)
IE Developer Toolbar includes a lightweight, easy-to-use Javascript profiler.
The Web Developer extension adds a menu and a toolbar to the browser with various web developer tools. It is designed for Firefox, Flock and Seamonkey, and will run on any platform that these browsers support including Windows, Mac OS X and Linux.
The DOM Inspector (also known as DOMi) is a developer tool used to inspect, browse, and edit the Document Object Model of documents – usually web pages or XUL windows. The DOM hierarchy can be navigated using a two-paned window that allows for a variety of different views on the document and all nodes within.
Venkman is the code name for Mozilla s JavaScript Debugger. Venkman aims to provide a powerful JavaScript debugging environment for Gecko-based browsers namely Firefox 3.x, the Netscape 7.x series of browsers, Netscape 9.x series, Mozilla Seamonkey 1.x and Mozilla Seamonkey 2.x.
JavaScript Shell is a command-line interface for JavaScript and DOM.
The solution is Firebug Lite, a JavaScript file you can insert into your pages to simulate some Firebug features in browsers that are not named “Firefox”.
NitobiBug is a browser-based JavaScript object logger and inspection tool – similar to Firebug. NitobiBug runs across different browsers (IE6+, Safari, Opera, Firefox) to provide a consistent and powerful tool for developing rich Ajax applications.
Alert()s are widely used to create checkpoints in JavaScript development. Blackbird offers a stylish console to log, view and filter messages in JavaScript, which quickens the development process by eliminating the pause at every alert and analyzing each better.
