Top 10 Uses of
JavaScript:
Below is the list of
top 10 uses of JavaScript are as follows:
1.Web Development:
JavaScript is a client scripting
language which is used for creating web pages. It is
a standalone language developed in Netscape. It is used when a webpage is to be
made dynamic and add special effects on pages like rollover, roll out and many
types of graphics. It is mostly used by all websites for the purpose of
validation. In addition to validations, it supports external applications like
PDF documents, running widgets, supporting for flash applications etc. It can
also load content into a document whenever the user requires it without even
reloading the entire page.
2.Web Applications:
With technology
browsers and personal computers have improved to an extent that a language was
required to create robust
web applications. When a user explores a map in Google Maps then
the user just needs to click and drag the mouse. All detailed view is visible
by just a click. This is possible due to JavaScript. It interacts with the
browser without sending messages to and fro to the servers. JavaScript uses
Application Programming Interfaces(APIs) that provide extra powers to the code.
3.Presentations:
JavaScript also provides
the facility of creating presentations as a website. JavaScript provides
RevealJS and BespokeJS libraries to build a web-based slide deck. Reveal.js
creates some of the most beautiful and interactive decks using HTML. A user can
easily insert nested slides. Even if the user is not aware of programming
language then they can easily build a site with so much help online. These
presentations are touch optimized and work great with mobile devices, phones,
and tablets. With all this JavaScript also provides different transition
styles, themes, and slide backgrounds. It supports all CSS color formats.
JavaScript also provides Bespoke.js plugin with a wide variety of features.
These include responsive scaling, animated bullet lists, and syntax
highlighting for code examples. It provides themes which are polished and not
too flashy. The quickest way to start Bespoke.js is using a generator. It
allows the user to set titles to your presentation and go through a set of
questions to get the plugins required.
4.Server Applications:
Node JS is built on
Chrome’s Javascript runtime for building fast and scalable network
applications. It uses event-driven, lightweight and efficient applications
which are to be distributed over the systems with the help of a server.
Javascript is used to handle HTTP requests and generate contents. When a user
is writing thick applications in JavaScript on the client then a user may even
write the logic in JavaScript on the server so that cognitive leaps can be done
from one language to the other.
5.Web Servers:
Using Node JS a web
server can be created. The advantages of Node JS are that it is event-driven
and would not wait for the response of the previous call. It moves to the next
call and takes advantage of events to get notifications when a response is
received for a previous call. The servers built on
Node JS are very fast and do not use buffering and transfers
chunks of data. In addition to this, it is single threaded with event looping
which is used in a non-blocking way. The HTTP module can help in creating a
server by using the createServer() method. This method is executed whenever
someone tries to access port 8080. In response to this, the HTTP server should
display HTML and should be included in HTTP header. It can be installed easily
by typing ‘npm install -g http-server’ and it can be started by typing
http-server command.
6.Games:
Not only websites but
uses of JavaScript also helps in creating games for leisure. The combination of
JavaScript and HTML5 makes JavaScript popular in games development as well. It
provides the Ease JS library which provides simple solutions for working with
rich graphics. It also has an API that is familiar to all flash developers with
a hierarchical display list. A user can create a Stage and it will render the
display list to its target canvas. Ease JS also has 2D bitmaps called Sprites
which are drawn directly to render the target for transformations.
7.Art:
Using the HTML5 in
JavaScript drawing graphics on a web page has become easier.
All two and three-dimensional shapes can be easily drawn on a canvas and this
has opened the browser as a new medium for all different digital art projects.
A canvas has no border and no content and hence lets the user create his own
art.
8.Smartwatch
Applications:
Javascript being the
most used language is because it is being used in all possible devices and
applications. uses of JavaScript provides a library Pebble JS which is used in
smartwatch applications. This framework works for applications that require the
internet for its functioning. Using Pebbles allows a developer to create an
application for a number of watches using JavaScript.
9.Mobile Applications:
The most important
thing that can be done by the uses of JavaScript is building applications
without web contexts. Mobiles being mostly available in Apple and Android two
different languages are used to build these. It should be possible to write
once and use it on both platforms of these devices. PhoneGap is the framework
which enables this. Also recently we have React Native that serves this
purpose. It is the major player in cross-platform changes and deployments.
Hence uses of Javascript can be used to deploy and download the respective
applications across cross environments.
10.Flying Robots:
Yes, even this is the
field that is not left untouched by JavaScript.Using Node Js a user can program
a flying robot.
