Whether you are a web developer
or know absolutely nothing about programming, you've probably heard of
JavaScript before. This programming language is mainly used in the design of
interactive web pages and mobile applications.
If you want to get into a web design company in Pakistan,
you need to learn JavaScript, especially if you are planning to become a
front-end developer. In this article, I will therefore tell you about
Javascript and its main applications and features.
What exactly is JavaScript?
First of all, we should not
confuse JavaScript with Java. Despite the confusion some people may have
between these two languages, the only thing they have in common is the word
“java” in their names. It is true that from the syntactic point of view they
are quite close, but not at all in their fundamental concepts.
JavaScript (or simply JS) is a
programming language, also called a scripting language, which allows you to
implement several elements of a high level of complexity on web pages, such as
animations, image galleries, variations of layouts, among others. With JS you
can even create games, 2D graphics, animated 3D animations, and much more.
Personally, I also use it to program connected objects, but I will come back to
this in a future article.
Applied to an HTML document , it
can bring interactivity to a site or a Web application, and make the user
experience much more dynamic and intuitive.
Originally created to work in the
Netscape Navigator browser, shortly after its release JavaScript was
incorporated into Microsoft's web browser (Internet Explorer), which helped
make it more popular.
The language that revolutionized
the World Wide Web
There was a time when the internet
was finally pretty boring. In its early days, the World Wide Web was just a
bunch of static HTML pages, with links pointing to each other. Over the years,
the needs of those who “surf” the Internet have become increasingly complex. So
we had to find a way to make user interaction with web pages easier and more
fun!
JavaScript is at the heart of the
technologies that have made the Web what it is today. Along with HTML and CSS,
JS enables the development of interactive web pages, which provides users with
a much more enjoyable experience.
So, we can say that the Web as we
know it is based on three pillars: HTML, CSS, and JavaScript.
·
HTML is the markup language we use to
structure and make sense of our web content. For example, by defining
paragraphs, titles, tables of content, or inserting images and videos on a
page.
·
CSS is the language that allows us to
format our web pages. We use it to style our HTML content. Style sheets, also
called CSS files, contain code that allows you to manage the design of a page
in HTML, such as defining colors, fonts, placing our content in multiple
columns, etc.
·
JavaScript is the language that will
allow us to develop dynamic content inside the HTML document to make our
website interactive. It is he who will bring a form of intelligence to the
whole because, unlike HTML and CSS, JavaScript is a real programming language
that allows you to create algorithms.
How is JavaScript different from other
languages?
The JavaScript allows developers
to work with a single programming language, either for the development
front-end (application or website - the customer) or developing back-end
(database, API, authentication, etc. - the server).
In a nutshell, front-end
development is about the design of the graphical user interface. Indeed, it is
the visible part of the application or the website, intended to be manipulated
by the client (also called client-side).
Back-end development involves
programming the server and application or website functionality. This is the
invisible part, without which the GUI remains an empty shell.
In summary, you can develop and
manage any aspect of an application or website design using just one
programming language: JavaScript.
Another big differential is that
the JS developer community is extremely active, responsive and open to anyone
who wants to venture out.
There are a plethora of forums
and services that make free resources available to developers, so almost any issue you will encounter while developing an app or website has already been
resolved by another developer.
Why JavaScript and not another language?
In life, there are often two
reasons why it is sometimes difficult to make a choice: either there are few
options to choose from, or there are too many. In programming, you are spoiled
for choice given the number of languages available: Python, Java,
JavaScript, Ruby, PHP, C # … and many others. How to make the right choice,
then?
A developer who has mastered
several programming languages is a highly skilled and in-demand developer.
However, you still have to start somewhere; And why not start by learning a
versatile and flexible language, which will allow you to develop Web and Mobile
?
Yes, you understood well!
JavaScript is the only versatile language that allows you to develop both
websites and mobile applications. If you are not yet convinced, here are some
good reasons to learn JavaScript :
It is the most popular
programming language
I'll start my list with the most
obvious reason. According to the Stack Overflow site , JavaScript is the most
popular programming language used by developers today. Even back-end developers
prefer JavaScript over other languages.
In addition, JavaScript gives you
a range of possibilities; this language has many uses which you cannot even
imagine. It works for example also with Smart TVs, with the Internet of Things
(IoT), can be used in the creation of native mobile applications for iOS and
Android, as well as cross-platform desktop applications (Windows, MacOS, Linux)
. It can even allow you to develop augmented reality and virtual reality
applications. Finally, be aware that all your browser extensions that you have
installed are made using JavaScript, it is the only language allowing this.
JavaScript is the ideal language to start
programming
As it is already installed on all
web browsers today (it is by the way the only one), you just have to start
coding. It is one of the most accessible languages to learn. Besides that,
there is a large community of JavaScript developers online that offers support
and advice.
JavaScript is also a great tool
for novice developers who want to expand their skills into other languages. If
you learn to code in JS, you will acquire skills such as object oriented
programming , and you will be able to apply these skills to any new language
such as Python, Java or C ++, for example.
JavaScript is a flexible and versatile language
It allows developers to manage
any aspect of the design of an application or a website. Do you want to do
front-end development? You can ! Are you more interested in the server side
(back-end)? With JavaScript it is also possible to do this. You can also build
Desktop, Mobile, and Web apps with Electron , React, and React Native . In
short, become a full-stack developer thanks to JavaScript.
With JavaScript you can even
create games. Games have become big business today, and developers who know
JavaScript have an added advantage in this market. The versatility, power and
ability of the JS to easily create visual effects make this language a perfect
choice for game designers.
With an increasing number of
businesses and organizations going digital, there is also a noticeable increase
in demand for developers who know the most popular programming languages. As I
have already pointed out, JavaScript is one of these languages.
And in terms of salaries, how
much does a JavaScript developer earn? On this side, know that you can have
incomes of up to 35K in CDI at the start. Not bad to start with, isn't it? And
let's not forget that it is also possible to work on your own, as a freelance
developer . You have the freedom to manage your time and work schedules without
having to depend on an employer.
How do you learn JavaScript, then?
As we have already seen,
JavaScript is essential for anyone wishing to start a career in Web and Mobile
development , which brings us to the next point: how to learn JavaScript ?
You will find a lot of free
content on blogs and online forums. Start by understanding what JavaScript is
and how it works. Then, you can try writing a few lines of code in your browser
and test them for yourself.
If you want to go further and
become a Web and Mobile developer in a very short time, it is possible! But, in
this case the ideal is to turn to intensive training , such as a bootcamp
coding . The objective of this type of training is to make you an autonomous
developer, specialized in a particular technology.
