When And
Where to Use JavaScript Libraries!!
When and where JavaScript libraries should be used? In this
article we are going to talk about few popular JavaScript libraries and their
uses.
As a popular client-side scripting language, JavaScript is
currently being used by almost all the websites. Also, for development of
cross-platform mobile applications, it is also being used by developers with
HTML5 and CSS3. Most developers use different JavaScript frameworks to reduce
development time and effort. Based on the specific needs of the project,
developers have the option to select from several popular JavaScript
frameworks, including AngularJS, Meteor, Backbone, Express and Plain Nodes.
However, it is always important for them to use each of these popular
libraries. So, let’s began with popular JavaScript libraries.
§
AngularJS
AngularJS is also distributed as a JavaScript file as it is
also written in JavaScript. It helps the programmer express clearly the
components of the application by expanding the HTML syntax. While creating
dynamic websites, programmers can use AngularJS to use HTML as template
language. They can easily add the library to HTML pages through the
<script> tag. They can use expressions to
bind the AngularJS data to HTML code. Similarly, they can define the AngularJS
app through the module, and can control the application through the
controllers. Developers must use this library to make single library websites
and web applications fast.
§
Meteor
The Open Source Framework enables programmers to create web
applications and mobile apps using JavaScript. The integrated isobuild system
provided by the meteor makes it easy for them to write codes once and for all,
it runs on both web browsers and mobile devices. They can also take advantage
of the cloud platform provided by the meteor to easily deploy, monitor, and
scale connected applications. Meteorite is considered to be the best JavaScript
framework for the development of real-time applications. It can also be used to
create websites and mobile applications using a programming language “JavaScript”.
§
Backbone
Programmer use data as models with the help of open source
JavaScript libraries. They also have the option of saving, modifying and
validating models along with saving on the web server. Due to some UI action
each time an attribute of the model changes results in changing of an event. It
can further inform all the views of the model to the changed state. Views can
respond to immediate changes, and provide updated information to end users. In
this regard, developers can use Backbone.js to build their web applications.
Additionally, the library can be used when programmers do not want to link
their data to the Document Data Object Model (DOM).
§
Plain NodeJs
NodeJs are completely different from other structures. This
is a cross-platform and server-side runtime environment for web applications.
This enables the programmer to create a JavaScript application that works
seamlessly with the major operating system. NodeJS executes code through the
Google V8 JavaScript engine. Most modules in NodeJs are written in JavaScript.
It comes with a built-in library that allows web applications to function as a
web server. Programmers can use nodes to run web applications directly on web
browsers without relying on any web server. Runtime environment is widely used
by large tech companies including Microsoft, IBM, PayPal and LinkedIn. Java
developers can use NodeJS to write server applications in JavaScript.
§
Express
The programmer also has the option of simplifying and
speeding NodeJs for application development by using such a framework as Express.
Express is designed as a NodeJs Framework written in JavaScript that web
programmers can use to build fast for the diversity of server applications.
Developers can use Express to create single-page and multi-page websites as
well as cross-platform mobile applications. They can also use Express as part
of the MEAN stack with MongoDB as the database and front end framework in the
form of AngularJs. As a result, developers can use Express to take advantage of
many useful features while availing NodesJS.
Conclusion:-
As a result, the features of the personal JavaScript
libraries are different. Therefore, in order to gain profits in terms of time,
quality and performance, professionals should not forget to compare the
AngularJS, Meteor, Backbone, Express and Plain NodeJs, depending on the
specific needs of the project.
