Today's World Wide Web is a dynamic environment, and its users set a high bar for both style and function of sites. To build interesting, interactive sites, developers are turning to JavaScript libraries such as jQuery to automate common tasks and simplify complicated ones. One reason the jQuery library is a popular choice is its ability to assist in a wide range of tasks.
Because jQuery does perform so many different functions, it can seem challenging to know where to begin. Yet, there is a coherence and symmetry to the design of the library; most of its concepts are borrowed from the structure of HTML and Cascading Style Sheets (CSS). Because many web developers have more experience with these technologies than with JavaScript, the library's design lends itself to a quick start for designers with little programming experience. In fact, in this opening chapter we'll write a functioning jQuery program in just three lines of code. On the other hand, experienced programmers will also be aided by this conceptual consistency, as we'll see in the later, more advanced chapters.
But before we illustrate the operation of the library with an example, we should discuss why we might need it in the first place.
Okey, let's begin, at first you may ask "What you have to know, before learning jQuery?"
Here's what you should learn before starting to learn jQuery:
1. HTML / XHTML
Better yet, if you complete your reading of the standard HTM / XHTML, XML.
2. CSS
How do you use a CSS Selector? id or classes?
3. JavaScript
Mastering Java Sript important so that you can compare the use JavaSript without jQuery with jQuery itself.
What you can do using jQuery?
1. Ease of access document element.
2. Modification of web page views.
3. Changing the contents of the document.
4. Responding to user interaction.
5. Animating: about changes made to the document.
6. Retrieving information from a server without a page refresh.
7. Simplified JavaScript common tasks.
jQuery, whether it's food? (Chapter 2)
jQuery is a powerful JavaScript library that can enhance your websites regardless of your background.
Created by John Resig, jQuery is an open-source project with a dedicated core team of top-notch JavaScript developers. It provides a wide range of features, an easy-to-learn syntax, and robust cross-platform compatibility in a single compact file. What's more, over a hundred plug-ins have been developed to extend jQuery's functionality, making it an essential tool for nearly every client-side scripting occasion.
Learning jQuery provides a gentle introduction to jQuery concepts, allowing you to add interactions and animations to your pages—even if previous attempts at writing JavaScript have left you baffled. This blog guides you past the pitfalls associated with AJAX, events, effects, and advanced JavaScript language features.

jQuery? Is it Free?
Yes, jQuery is for free. jQuery is available in two types of MIT and the GPL license. You can choose which license is right for you.
I'm an Programmer for particular programming language, is jQuery right for me?
Oh, it depends on you ... :)
I can not answer that, importantly, jQuery is not more difficult than other Java Script framework.
Suitable to be applied, whether it's your ASP programmers, PHP, JSP, Rails, and others. Surely during your goal is to use jQuery to manipulate the DOM using Java Script.
Who's already using jQuery?
Among others: Google, Amazon, IBM, Microsoft, Twitter, Intel, Oracle, Digg, Dell, and others.

jQuery, whether it's food?
Before we started using jQuery is a good idea that we understand exactly what jQuery.
As mentioned in jQuery official website, (www.jquery.com), jQuery is::
Yes, that's all.
If you are accustomed scripting with JavaScript, you will discover the pleasure of using jQuery. You no longer need to write hundreds of lines of Java Script. jQuery make it simple.
Why jQuery? Is not there a lot of Java Script libraries other, more powerful?
Maybe you're stuck on this blog because I was looking for Java Script libraries which ones should you use and start comparing to make a choice. Whatever your choice, that is best for you.
But, believe me, jQuery is easier to learn compared to other similar Java Script libraries. This is where the excess, jQuery is more well-documented. Tutorials, plugins and the UI is also very much (try for googling..). Very suitable for beginners in programming due to jQuery AJAX is not used for functions outside the DOM is very complex.Please read an interesting article about the comparison with Mootools jQuery here: http://jqueryvsmootools.com/
