jQuery Lint is a simple script, used with the JQuery library, that diligently reports errors and any incorrect usage of jQuery. To some extend, it also offers guidance on best practices and performance concerns. Unline JSLint, this plugin is a runtime reporter. To use it, you need to include it after JQuery in your document.
If you pass incorrect arguments to any method, jQuery Lint will let you know. It compares your arguments with the argument signatures in jQuery’s API. To see the errors reports, you can either use FireBug or you can quite easily plug-in your own console mechanism.
