How Good is JavaScript for Web Apps!!
How perfect is the Javascript to build
a large scale Web Applications? This whole article is answering this question
so, let’s have a look over it.
According to recent statistics
posted on W3techs.com, over 89% of websites currently use JavaScript as a
client-side programming language. As a cross-platform and light programming
language, Javascript makes it easy for developers to create responsive websites
and web applications that work seamlessly with popular web browsers, operating
systems and devices. It
is widely used by programmers as part of the web browser to accomplish important
functions such as web browser, user interaction and unlimited communications.
Additionally, the
programmer has the option of using Javascript as a server-side scripting
language through Node.js and similar runtime environments. Also, they can use
different types of open source frameworks to reduce the time and effort needed
to build JavaScript applications. It can also be used with HTML5 and CSS to
create web applications and games. So you can consider using Javascript as a
dynamic client-side programming language to build large-scale web applications.So, let’s look over the advantages of using Javascript for Web Application
Development.
v
Major Web browser supports:-
Javascript is
supported by most widely used web browsers including Firefox, Chrome, Internet
Explorer, Safari and Opera. It is also supported by the new web browser whose
vendors have implemented Javascript. Users can access web applications using
Javascript despite their choice of Java browser. They also have the option of
accessing all the functionality of the website by enabling the scripting
language, if it is disabled for some reason.
v Any specific tool is not needed:-
Javascript is an
interpreting programming language. You can easily write code without using a
specific device or program. You can just open a notepad, and start writing
javascript code. Also, you have the option of using many editors to identify
mistakes in the code. The editors make the script colorful or re-iterable to
make users easier to identify errors.
v Code can be reused:-
By placing the
code in different files, you can reuse the javascript code on many pages. After
placing the code in a separate file, you have to save the file with the extension
“.js”. The file can be linked to several web pages using the <script> tag
in the HTML code of the page. The option enables you to avoid writing
additional code while adding the same functionality to different parts of the
website.
v Updated Response data is delivered
from the server:-
Javascript uses
the XmlHttpRequest API for further data retrieval. The API sends an HTTP or
HTTPS request to the web server, and loads the response sent by the server to
the script. The script can easily update the current web page based on the
response data received from the server without reloading a new web page. Therefore,
you can promote the display of web applications by providing updated
information to users without fully loading the web page.
v Works comparatively faster:-
AS, JavaScript is
comes under client-side scripting language. The code is executed on the user's
system. Since code is executed without interaction on any server, processing is
done relatively quickly. Rapid processing enables web applications to keep busy
by providing users with a rich browsing experience.
v Contains many Libraries and Frameworks:-
You have the
option of reducing the time and effort needed to build large JavaScript
applications using many structures and libraries. Many programmers prefer to
use dynamic javascript frameworks such as AngularJS, Backbone, Amber and React.
However, you still have the option to select from a longer list of JavaScript
libraries according to your specific requirements.
v Website’s Functionality is extended:-
Javascript makes
it easy for you to expand the functionality of the web application without any
extra effort. You can use the scripting language to create visual effects on
the screen, calculate data and make web pages more interactive. Javascript
further allows you to extend the functionality of the website using third-party
scripts. Flexibility makes it easy to add out-of-box features to web
applications without using any additional plug-ins or tools for you.
v Local Caching is optimized:-
Javascript with
HTML5 can be used to enable users to access websites, even when there is no
active Internet connection. Techniques are effective at caching data locally,
and make web connections accountable until the internet connection is restored.
You can also use tools like Condo UI DataSource to track changes made in the
object locally, and upload changes to the web server after the network
connection is restored. The option enables you to work the web app like a
mobile app.
v Load on Server is reduced:-
Server-side
scripting languages require a web server to process a user
request before sending a response to the user. So the user needs extra time
even after having a high speed internet connection. But JavaScript code is
processed on a user's machine without interacting with a web browser. Thus, the
stress and load on the web server is very low, while the user receives quick
response. You can use Javascript while building websites on a large scale to
provide users with a fast response without putting extra stress on the server.
v Also works with other Web technologies:-
As previously mentioned,
Javascript can be used as both client-side and server-side scripting languages.
Also, you have the option of using JavaScript as a client-side technology with
some of the most widely used web technologies, such as PHP, Pearl and Java. Scripting
language is widely used with HTML 5 and CSS for the development of responsive
websites accessible on different devices using the same code base.
Conclusion:-
However, when
making use of it to build large websites and web applications, some major
drawbacks to Javascript should be kept in mind. Since the javascript code is
executed on the web browser, it becomes weak for various security attacks.
Also, the code becomes unpredictable because individual browsers consider it
different.
But you can still
use JavaScript with many popular web technologies like HTML5 and CSS so that
strong web applications can be available on many devices, operating systems and
web browsers.
