In this tutorial, we’ll look at how Dijits work and how Dojo can help you write some powerful web applications.
If you’re like me, you’re reading this on your bright-red custom-built laptop in a soothing rosemary-scented bubble bath, and you’re wondering, “Why do I want another interpreted programming language? I can find my way around Perl and PHP and maybe a little Python. And Unix shell scripting. I feel fine. Why do people keep talking about Ruby?”
If you’ve built a few websites from scratch, chances are you’ve noticed that you have to solve some of the same problems over and over again. Doing so is tiresome and violates one of the core tenants of good programming — Don’t Repeat Yourself (DRY).
Luckily for you other people long ago noticed that web developers face similar problems when building a new site. Sure, there are always edge cases which will vary from site to site, but for the most part there are four general tasks we developers have to handle — Create, Read, Update and Delete, otherwise known as CRUD.

Popular Ajax library jQuery is celebrating its fourth birthday with a major new release — JQuery 1.4.
The latest version of jQuery boasts some impressive speed gains and represents a ground up refactoring of much of jQuery’s underlying code. According the jQuery’s developers this release is significantly faster across browsers and eliminates much of the redundancy in jQuery’s internal functions.
Other nice changes in this release include support for HTML5 elements in serialization calls, the ability to test for specific rendering engines (for example, target WebKit with jQuery.browser.webkit) and support for per-property easing in your animations.
