For most PC users around the world, JavaScript is a formidable term. As Brian Kemp, a 28-year-old accountant from New York, says, "I've been using a PC for the past 18 years and the Internet for 10 years, and in all this time, I never felt the need to acquaint myself with JavaScript." That was until his web browsing grew increasingly fraught with JavaScript errors cropping up every now and then. "Once I began reading up on JavaScript basics, I realized that it was not the exclusively technical territory that I had taken it to be," admits Brian.

Because scope in javascript can be the source of very hard to track bugs, we will see how work the variable scoping in javascript. Depending on your programming languages background (block level scoping or not), you may have some surprises.
For this post, I’m going to be using jQuery, because it’s the closest well-known thing to the library I’m currently working on at my new job. (It’s a wrapper for YUI with lots of syntax niceties.)
Programming asynchronous actions is a pain in the head. Why can’t I do setTimeout($(’#myNode’).hide, 2000)? I need to bind the hide function to the $(’#myNode’) object for starters, and jQuery doesn’t give you a bind method, and besides, binding and execution scope gives lots of JavaScript novices a headache. Wouldn’t this be nice:

The various client-side technologies differ in many ways, starting with the way they get loaded and executed by the web client. JavaScript is a scripting language, whose code is written in plain text and can be embedded into HTML pages to empower them. When a client requests an HTML page, that HTML page can contain JavaScript. JavaScript is supported by all modern web browsers without requiring users to install new components on the system.
I see a lot of person talking about how ajax is cool and it helps you doing things that you couldn’t do before it was “invented”. What most of these people don’t know is that most of the coolest features are not ajax. Ajax is just a way to communicate between a client and a server without reloading the whole page. The rest of it is javascript, DHtml (dynamic Html) and CSS (cascading style-sheet).

Picture yourself on a beautiful beach on a warm day. The sounds of the waves is music to your hears. You’re on a comfortable chair with a laptop on your knees connected via an incredible WiFi. You’re using a brand new web2.0 application that must be the gratest web site on the web. Then, you see an infamous alert from javascript…

You've seen images on web sites that putting your cursor
over an image causes the image to roll over into another
image. This article shows you a method that also tells the
browser to preload the second image.
A preloaded image bypasses the pause that would otherwise
be present the first time a rollover is called for.

The concept is deceptively simple. Yet, the protection is as good as having hidden file names on the server.
The site visitor types a password in a form.
{mos_sb_discuss:23} JavaScript can be embedded within the source code of a web page. Or, it can be in a file somewhere else and a special JavaScript tag used to insert the file when the web page is loaded into a browser.

JavaScript can be used to create an image object (an area in computer memory that holds the details the browser will need to display an image). No HTML code is needed.
