9 Most In-Demand Programming Languages
1. SQL
It’s no surprise SQL (pronounced ‘sequel’) tops the job list
since it can be found far and wide in various flavors. Database technologies
such as MySQL, PostgreSQL and Microsoft SQL Server power big businesses, small
businesses, hospitals, banks, universities. Indeed, just about every computer
and person with access to technology eventually touches something SQL. For
instance, all Android phones and iPhones have access to a SQL database called
SQLite and many mobile apps developed Google, Skype and DropBox use it
directly.
2. Java
The tech community recently celebrated the 20th anniversary
of Java. It’s one of the most widely adopted programming languages, used by
some 9 million developers and running on 7 billion devices worldwide. It’s also
the programming language used to develop all native Android apps. Java’s
popularity with developers is due to the fact that the language is grounded in
readability and simplicity. Java has staying power since it has long-term
compatibility, which makes sure older applications continue to work now into
the future. It’s not going anywhere anytime soon and is used to power company
websites like LinkedIn.com, Netflix.com and Amazon.com.
3. JavaScript
JavaScript – not to be confused with Java – is another one
of the world’s most popular and powerful programming languages, and is used to
spice up web pages by making them interactive. For example, JavaScript can be
used to add effects to web pages, display pop-up messages or to create games
with basic functionality. It’s also worth noting that JavaScript is the
scripting language of the World Wide Web and is built right into all major web
browsers including Internet Explorer, FireFox and Safari. Almost every website
incorporates some element of JavaScript to add to the user experience, adding
to the demand for JavaScript developers. In recent years JavaScript has also
gained use as the foundation of Node.js, a server technology that among other
things enables real-time communication.
4. C#
Dating from 2000, C# (pronounced C-sharp) is a relatively
new programming language designed by Microsoft for a wide range of enterprise
applications that run on the .NET Framework. An evolution of C and C++, the C# language is simple, modern, type
safe and object oriented.
5. C++
C++ (pronounced C-plus-plus) is a general purpose
object-oriented programming language based on the earlier ‘C’ language.
Developed by Bjarne Stroustrup at Bell Labs, C++ was first released in 1983.
Stroustrup keeps an extensive list of applications written in C++. The list
includes Adobe and Microsoft applications, MongoDB databases, large portions of
Mac OS/X and is the best language to learn for performance-critical
applications such as “twitch” game development or audio/video processing.
6. Python
Python is a general purpose programming language that was
named after the Monty Python (so you know it’s fun to work with)! Python is
simple and incredibly readable since closely resembles the English language.
It’s a great language for beginners, all the way up to seasoned professionals.
Python recently bumped Java as the language of choice in introductory
programming courses with eight of the top 10 computer science departments now
using Python to teach coding, as well as 27 of the top 39 schools. Because of
Python’s use in the educational realm, there are a lot of libraries created for
Python related to mathematics, physics and natural processing. PBS, NASA and
Reddit use Python for their websites.
7. PHP
Created by Danish-Canadian programmer Rasmus Lerdorf in
1994, PHP was never actually intended to be a new programming language.
Instead, it was created to be a set of tools to help Rasmus maintain his
Personal Home Page (PHP). Today, PHP (Hypertext Pre-Processor) is a scripting
language, running on the server, which can be used to create web pages written
in HTML. PHP tends to be a popular languages since its easy-to use by new
programmers, but also offers tons of advanced features for more experienced
programmers.
8. Ruby on Rails
Like Java or the C language, Ruby is a general purpose
programming language, though it is best known for its use in web programming,
and Rails serves as a framework for the Ruby Language. Ruby on Rails has many
positive qualities including rapid development, you don’t need as much code,
and there are a wide variety of 3rd party libraries available. It’s used from
companies ranging from small start-ups to large enterprises and everything
in-between. Hulu, Twitter, Github and Living Social are using Ruby on Rails for
at least one of their web applications.
9. iOS/Swift
In 2014, Apple decided to invent their own programming
language. The result was Swift – a new programming language for iOS and OS X
developers to create their next killer app. Developers will find that many
parts of Swift are familiar from their experience of developing in C++ and
Objective-C. Companies including American Airlines, LinkedIn, and Duolingo have
been quick to adopt Swift, and we’ll see this language on the rise in the
coming years.
Any great craftsman has a belt full of tools, each a perfect
choice for certain situations. Similarly, there will never be just a single
programming language, and each language will evolve and improve over time to
keep pace with innovation.
