Google Closure Compiler is a tool for making JavaScript download and run faster. It is a true compiler for JavaScript. Instead of compiling from a source language to machine code, it compiles from JavaScript to better JavaScript. It parses your JavaScript, analyzes it, removes dead code and rewrites and minimizes what’s left. It also checks syntax, variable references, and types, and warns about common JavaScript pitfalls.
YUI Compressor The YUI Compressor is JavaScript minifier designed to be 100% safe and yield a higher compression ratio than most other tools. Tests on the YUI Library have shown savings of over 20% compared to JSMin (becoming 10% after HTTP compression). The YUI Compressor is also able to compress CSS files by using a port of Isaac Schlueter‘s regular-expression-based CSS minifier.
JSLint is a JavaScript program that looks for problems in JavaScript programs. It is a code quality tool. JSLint takes a JavaScript source and scans it. If it finds a problem, it returns a message describing the problem and an approximate location within the source. The problem is not necessarily a syntax error, although it often is. JSLint looks at some style conventions as well as structural problems. It does not prove that your program is correct. It just provides another set of eyes to help spot problems.

LiveValidation is a small open source javascript library built for giving users real-time validation information as they fill out forms. Not only that, but it serves as a sophisticated validation library for any validations you need to make elsewhere, it is not just limited to form fields.
The naming conventions and parameters of the validations are similar to those found in the Ruby on Rails framework, and as such is the perfect companion. Don???t worry if you dont use Rails though, LiveValidation can be used anywhere you like, is simple to learn, and a joy to use.
Two versions are provided – a prototype.js version (ideal for use with Rails), and a standalone version (for using with any other javascript framework, or when having one at all would be overkill). Both are fully tested on most modern browsers with a comprehensive test suite.
Timeago: Timeago is a jQuery plugin that makes it easy to support automatically updating fuzzy timestamps (e.g. “4 minutes ago” or “about 1 day ago”).
Flexselect: Flexselect is a jQuery plugin that turns select boxes into flex-matching incremental-finding controls. Think of it as Quicksilver squished into a select box.
Facebox: Facebox is a jQuery-based, Facebook-style lightbox which can display images, divs, or entire remote pages. It’s simple to use and easy on the eyes.
The Vista-like Ajax Calendar (vlaCalendar) version 2 is a unobtrusive web version of the slick and profound Windows Vista taskbar calendar, by using the MooTools javascript framework, AJAX, XHTML, CSS and PHP.
Key features:
We start this project for self-use. Because it’s standalone we share it with other people who need to build a calendar/appointment or scheduling application. By and by, more and more people love it and hope us to maintain such a project.
Recently we decide arrange resources to this project for maintenance and further development. So we just have got a new home for wdCalendar.
https://sourceforge.net/projects/jqeventcalendar/
Over there we have svn/bug tracking/forum system. Please go there for more support.
Flexigrid Lightweight but rich data grid with resizable columns and a scrolling data to match the headers, plus an ability to connect to an xml based data source using Ajax to load the content.
