Great little site listing really useful small JavaScript libraries for all sorts of uses.

"Jash is a DHTML-based window that gives you command-line JavaScript access to the current browser window. With this console you can quickly debug scripts, manipulate the DOM, view the current page's objects, functions, and variables, execute arbitrary Javascript, enter new CSS (in IE, Firefox, Opera, and Safari), and much more." - A useful tool to execute JavaScript, make live (temporary) CSS changes to a page, discover the page structure, etc. for developers. Written totally in JavaScript so can be used on any platform with any browser. Include in your own pages for debugging or load via a bookmarklet to run on any page.

WYSIWYG edit component

"The jQuery Cycle Plugin is a lightweight slideshow plugin. Its implementation is based on the InnerFade Plugin by Torsten Baldes, the Slideshow Plugin by Matt Oakes, and the jqShuffle Plugin by Benjamin Sterling. It supports pause-on-hover, auto-stop, auto-fit, before/after callbacks, click triggers and many transition effects. It also supports, but does not require, the Metadata Plugin and the Easing Plugin." This is one that really works and is genuinely easy to set up - no complex CSS like so many of these things. It also works very well with just text or other HTML structures.

Eloquent JavaScript is a digital book providing a comprehensive introduction (tutorial) to the JavaScript programming language. Apart from a bookful of text, it contains plenty of example programs, and an environment to try them out and play with them. The book is aimed at the beginning programmer ― people with prior programming experience might also get something out of it, but they should not read chapters 2 to 5 too closely, because most of the concepts discussed there will probably be nothing new to them. Do make sure you read the end of the first chapter, which has some essential information about the book itself. The book is freely available, and may be used (as a whole or in parts) in any way you see fit, as long as I am credited as the original author. A copy of the book for off-line reading can be downloaded as a zip file, and a more easily printable version can be found here.
