Programmers who aspire to achieve greatness need to know what languages to learn. And the best way to do so is to know the 7 most in-demand programming languages of 2019.
They need to select the right education and work on a very particular set of skills that will impress future employers. This way, they’re guaranteed to land their dream job.
So, what are the most in-demand programming languages of 2019? And are which one is the best to start learning?
We’ve crafted a list of the 7 most in-demand programming languages of 2019 based on the current job postings on the market.
The top 7 most in-demand programming languages of 2019 are:
- Java – ~65,000 jobs
- C++ ~ 37,000 jobs
- Python ~62,000 jobs
- JavaScript ~ 39,000 jobs
- C# ~ 28,000 jobs
- Perl ~ 14,000 jobs
- PHP ~ 17,000 jobs
The job posting data is fetched from Indeed as of January 2019.
Comparing the data from last year, there’s a tremendous rise as a whole on job postings. The ranking, on the other hand, has not changed significantly.
Java is still on top and is followed very closely by Python. This is a clear indication that Python is on the rise.
JAVA
This year Java grew by somewhere close to 6% compared to last year, which was close to 62,000 job postings. Java is close to celebrating 24 years of its first release, and it has definitely stood the test of time.
Java was developed by a Canadian computer scientist that was working with Sun Microsystems at the time, James Gosling.
It’s a language that lets coders “write once, and run it everywhere you want”, also known as (WORA). This indicates that its compiled code can run on almost any platform without recompilation. This is what allows Java to be on top of every list when it comes to programming languages.
Java is majorly used for application development, such as:
- Desktop applications
- Website applications
- Android applications
- Big data manipulation
- Cloud computing
- Robotics
Python
Python was released more than a decade ago and has had a great rise ever since. It was designed and developed by Guido van Rossum, a Dutch programmer.
It’s considered a high-level language that is used to “glue” other languages to connect to large existing software components.
Additionally, it’s an object-oriented programming language (OOP). It’s well known to offer a vast collection of useful libraries for programmers and developers.
Python is dubbed as simple and easy to learn, with a very clean and readable syntax that decreases the time and the cost of maintenance.
There are a lot of uses of Python, like in applications, multiple programming paradigms, robust standard library, access of database and in a lot of other cases.
And this year, Python skyrockets with an increase of about 24% with approximately 62,00 job postings compared to last year’s 45,000.
JavaScript
Where would the website industry be without good old JavaScript?
JavaScript is an object-oriented programming language too, created by the American technologist Brendan Eich. Interestingly enough, it was inspired by Java. At that time Java was very popular so it “used” the fame of Java to gain attention and got the name JavaScript.
“Java to JavaScript is the same as car to carpet”
JavaScript doesn’t create stand-alone apps, and it can only run on browsers and the main aim is to make them interactive. It can be used to change and update HTML and CSS too.
One of the main reasons why JavaScript is so popular is because of its speed. It runs immediately within the browser and doesn’t need compiling on the client-side.
JavaScript has a lot of great frameworks you could use, such as:
- Angular
- React
- VueJs
- Ember
- Node.js
- Aurelia
- Backbone.js
This year, JavaScript postings didn’t change that much and yet it’s still in the top three!
C++
The C++ language was designed and developed as an enhanced version of the C language by Bjarne Stroustrup, a Danish computer scientist. Its four-year development started back in `79 and was released only in 1983.
C++ is mostly used for:
- Game development
- Drivers
- Client-server apps
- System software
- Application software
- Embedded firmware
This year, C++ had an increase in popularity by a whopping 16.22% compared to last year’s 37,000 job postings.
C#
The C# language is a Microsoft (MS) programming language, which is kind of a hybrid between C++ and C languages.
It allows developers and coders to build very secure applications such as XML web services, client-server, Windows client applications to run on the .NET framework.
In general, C# is easy to learn – but also complex. Does that make sense? C# has a lot of features that makes it easy to learn.
It’s a high-level language, and it’s very relatively easy to read. With most of the complex tasks away, the programmer doesn’t have to worry about them. One of the complex tasks is memory management. If you use C#, that’s one less thing you have to worry about because it’s handled by .NET’s garbage collection scheme.
C#’s job postings haven’t grown at all over the year, but it still remains one of the most popular languages on the market.
PHP
PHP is an acronym for Hypertext Preprocessor was created by Rasmus Lerdorf, a Danish programmer.
It’s an open-source, general-purpose scripting language that is used for web development. It can be embedded into HTML code from the server-side execution.
It’s very commonly used to draw data from a database on web pages.
There are three main areas where PHP scripts are used:
- Server-side scripting – This is the most popular and traditional field for PHP. You will need three things to make this work: The PHP parser (CGI or server module – your choice), a web server and a browser. You need to run the webserver with a connected PHP installation, and then you can access the PHP program output with the browser.
- Command-line scripting – You can make a PHP script to run it without having to run any server or browser. All you need is the PHP parser to use it this way. This kind of usage is ideal for scripts that are repeatedly executed using cron or Task Scheduler.
- Writing desktop applications – PHP is not well known in creating desktop apps with a graphical user interface at all. But, if you have the proper knowledge and would like to use some advanced PHP features you can use PHP-GTK to write these kinds of programs.
PHP job postings increased by 2,000 compared to last year.
PERL
The Perl language also made the top 7 most in-demand programming languages of 2019 list too!
PERL made its first appearance way back in `87, and it was designed and developed by Larry Wall, and American programmer.
Though Perl is not officially an acronym, it’s stated that it is an acronym of Practical Extraction and Report Language. But very few people choose to call it that because of the long name, so they go with PERL.
In general, Perl is a very stable, cross-platform programming language. It’s used for mission-critical projects in the public as well as the private sectors.
Perl has a lot of great features you could make use of, such as:
- Database integration interface DBI supports third-party databases (Oracle, Sybase, Postgress, etc,)
- Works great with HTML, XML and other mark-up languages
- Supports Unicode
- Is Y2K compliant
- Supports both procedural and object-oriented programming
- Interfaces with external C/C++ libraries through SWIG
According to Wikipedia, it’s a “family of two high-level general-purpose dynamic programming languages, Perl 5 and Perl 6″.
Perl’s popularity didn’t increase this year, but it remains one of the most popular and relevant languages to learn.
