JavaScript is a simple scripting language invented specifically for use in web browsers to
make websites more dynamic and attractive. On its own,
HTML is capable of outputting more-or-less static pages.
Once you load them up your view doesn't change much until you click a link to go to a new page.
Adding JavaScript to our code allows us to change how the document looks completely, from changing
text, to changing colors, to changing the options available in a drop-down list
and much, much more!.
Here in JavaScript we will see that
JavaScript is used in web development from several years and a number of
benefits we were using while development of websites. The major benefit of JavaScript is to add
more interaction between the
web pages and its viewers at very very low cost of a little extra work by web developer.
JavaScript allows web masters to get more out of their website than
HTML
and CSS can provide same we
will say to you make our web site more attractive
with JavaScript and develop your own skill. Its quite easy and too much
interesting to learn and all of us will be very exited while learning this
JavaScript Tutorial.
Definition of JavaScript, we can say it is client-side scripting language in
shortest definition. This means
the web browser will be running the script and we will learn that there are two
type of scripting languages in the entire web development one is Server side
scripting language and second is Client side scripting language. Like ASP,
PHP, JSP these are server side Scripting Languages and JavaScript, VB Script
etc are Client Side Scripting Languages.
The difference is only one, that Server Side Scripting Language will execute on web
servers like IIS, Apache, Jakarta Tomcat and Client Side Scripting Languages such as
JavaScript or VB Script will execute on client's browser, so we can see the coding or
logics also by using view source of our web pages. JavaScript will be available on view
source of each web page but Server side script will generate out put in
HTML and push
it to client side, so when we use view source no script will be available only
HTML
will be on view source.
There are several uses and abuses for the JavaScript language.
The only few things we want to share now, these things are in our daily use
while browsing or web development. Such as mouse interactions like
animations, popup, sliding, classes, form validations, status bar use, time and
dates representations, buttons, menus and much more we will learn while reading this
JavaScript Tutorial.
