If we see deeply there
are many computers languages that are used for different purposes. The demand
and popularity of these programming languages changes every year, and also new
languages are introduced with the most amazing features but the question is
that which programming languages we must learn. I have discussed about five
most demanding languages that we should learn:
Python
Python is most widely
used programming language with the variety of different applications. Python
was developed by Guido Van Rossum in 1990s. Python is considered as the top
programming language overall.
At the beginning level
python tried to overcome the barriers of programming, even school kids can also
write production grade code.
Common Uses
The main use cases in
which python is used:
·
Artificial Intelligence
·
Deep Learning
·
Web Development
·
Data Science
·
Data Analytics
·
Games Applications
Limitations
We cannot use python
for the applications of mobile development.
Job Availability
It is considered that Python
developers make a highest salary as compared to other programming languages. It
is the most demanding programming language in USA Job market with the highest
number of Job and Average Annual salary $120K in 2020.

Java
Java is strictly
backward compatible language, which is commonly associated with the development
of client server applications, which is used by large business around the
world.
Java’s runtime, Java Virtual Machine is
standard of software engineering and the best virtual machines in the market.
Common Uses
The main use cases in
which java is used:
·
Android mobile Operating System
·
Large Data
·
Enterprise Application development
·
Web Development
Limitations
Platform limitations
(available only for Macintosh, Window 95/NT, Sun Solaris)
Java is not optimal
for applications that run on the cloud as averse to the server.
Job Availability
Java is also the most
demanding language in the world. Java developers make the annual salary
$104,000 because its outstanding features include powerful memory management,
best performance, backward compatible, top-notch security and provides many
jobs in the market.

C/C++
These are popular high
languages. C was developed by Dennis Ritchie at AT&T Bell Laboratories in
1972. The C language was originally designed to write system programs under
UNIX operating system. Its power and flexibility made it popular in industry
for wide range of applications.
Bjarne StrouStrup from
Bell labs started the development of C++ language in 1980. The first commercial
release of the language appeared in October 1985. It was originally named “C”
with classes. It was an enhancement to C language. It allows the use of a
programming technique known as Object Oriented programming.
Common Uses
The main use cases in
which C and C++ is used:
·
System programming
·
Game Development
·
IOT and real-time system
·
Machine learning
·
Deep learning
·
Embedded systems
·
Distributed systems
Limitations
If we talk about C
language, its syntax is complex and not suitable for more modern use cases such
as website or mobile application. The C++ language is complicated as compared
to other programming because of its complex syntax.
It also does not support
run-time checking, which is a method of detecting errors or defects while
software is running.
Job Availability
If we see in USA
market, there are 28k jobs posting for only c developers. C++ is considered a
very demanding programming language with 41k jobs posting. Also C++ developers
make $108k per annum which places it in 5th place.

Javascript
For developing
interactive websites, javascript is the most popular language. When combined
with Node.js, Javascript can be used to produce web content on the server
before a page is sent to the browser; it can be used to develop games and
communication applications that run directly in the browser.
Common Uses
The main use cases in which
Javascript is used:
·
Web development
·
Backend Development
·
Mobile App Development
·
Serverless Computing
·
Browser Game Development
Limitations
JavaScript does not
have any multiprocessor capabilities and also it cannot be used for networking
applications.
Job Availability
In the USA Job market,
indeed JavaScript has been ranked as the third most demanding programming
languages with 57k jobs posting in 2020 with $114k average year salary.

PHP
PHP is another
programming language developed by a software engineer Rasmus Lerdorf to create
dynamic web applications. Later, many features were added to PhP.
Now it is one of the
highly productive server-side web development programming languages. In the
market, there are many successful and stable PHP frameworks.
Common uses
The main use cases in
which PHP is used:
·
Developing CMS Systems
·
Server-side web application
development
·
Standalone web application on
development
Limitations
PHP popularity has
dropped because python and Javascript have gained popularity.
Not suitable for large
applications.
Poor error handling
method.
Job Availability
In USA job market, PHP
has been ranked as the 7th most demanding programming languages with
18k jobs in 2020 and their developers can expect an average year salary $90k.
