For the most part Javascript is used to make web pages dynamic, move elements on the page, highlighting areas of the page, bringing in new content from the server, etc. There are other cases though like node.js where it's used as a server to make the web pages themselves. There are also a few cases outside of the web world where javascript can be used, some robotics, etc.

∙ 13y agoJQuery is a javascript library. It's extremely easy to use, and it abstracts away many of the browser compatibility issues present in javascript. Save yourself some time and give it a shot. Other libraries exist-- to name a few prototype, scripts.aculo.js, moo tools, and YUI.
Check out jquery's web page and some demos.

∙ 12y agoAJAX and Javascript refer to two different concepts.
AJAX stands for Asynchronous Javascript and XML -- it's how websites can load information from the server without refreshing the page.
Javascript is an entire client-side language that does a lot more than just client-server communication.

∙ 10y agoJavascript, can be used to add 'interactivity' to otherwise boringly 'static' HTML web pages; HTML web pages do usually consist of a mixture of dull 'text/graphics' which doesn't move; instead, you just merely stare at it.
For example, when the web page loads you could automatically display a Javascript dialog output message:-
<body onLoad="javascript:alert('Thanks for visiting my web page!');">
Or, if a mouse event occurs such as a form button having been clicked on; then, a Javascript dialog alert message box might suddenly appear.
<form>
<input type="button" value="Click me" onClick="alert('Thanks for clicking!');" />
</form>
Javascript, may also be used to collect input directly from the web page user themselves; again, through the use of dialog boxes.
<script>
number=prompt("Enter a number","Type your number here...");
alert("You typed: " + number);
</script>
As well as, using Javascript to interact with the user through various dialog box messages; it's also possible to get Javascript to write code directly into the web page itself...
<script>
document.write("Hello, world! From Javascript");
</script>
These are all extremely simple 1 or 2 line examples of Javascript code. Using multiple lines of Javascript code; then, it's actually possible to play Javascript games/create and run animations/-etc.
Here is an example of a Javascript program using multiple lines of code...; all this program does is output the 7 times tables:-
<script>
var timesTablesNumber=7;
for (var x=1; x<=12;x++){
document.write(x + " X " + timesTablesNumber + " = " + x*timesTablesNumber + "<br />");
}
</script>
...if you wish the above Javascript program to output a different number times tables; then, change where it says: 7...to become some other number, instead; such as: 8.
Most people start out by learning to write extremely simple 1 line Javascript programs; and, then, over time progress on to learning how to write much longer programs, instead; possibly, consisting of many 10's/or, even 100's of lines of Javascript code. In order to be able to achieve doing that, though; takes much time, effort, patience, practice.
The really good thing about attempting to learn Javascript coding now-a-days is there are many FREE tutorials available online; some of which it's even possible to follow along and do 'interactive' coding...by running the program you wrote...then, viewing the actual output results, immediately, right away...all from inside of your web browser itself. See below for a list of links...

What does acronym Ajax stand for?

What set of frameworks or libraries would you use for creating an Ajax web application?
There's no debate that JavaScript is the most widely used language client-side on the Web. We are using JavaScript for everything, from form validations to full Ajax applications.

Tell you about asynchronous JavaScript and XML?
I do not know in depth. But using the Asynchronous Javascript and XML HTTP Request one can easily access the concept of AJAX. simply ajax is an technique of many technologies such as Javascript, XMLhttprequest, css and dom.
