The 7 Most In-Demand Programming Languages of 2019

Aspiring developers need to know what languages to learn; they need to select the right education and work on a skill set that will impress future employers and land their dream job. So what are the top programming languages? And what is the best one to learn? We’ve compiled a list for you that highlights the most in-demand programming languages based off current job postings on the market.

Here are the Top 7 programming languages with most job posting on Indeed as of January 2019:

  • Java – 65,986 jobs
  • Python – 61,818 jobs
  • Javascript – 38,018 jobs
  • C++ – 36,798 jobs
  • C# – 27,521 jobs
  • PHP – 16,890 jobs
  • PERL – 13, 727 jobs

Compared this year’s January data to the data we collected last January 2018, on this same topic, job postings are on the rise as a whole. The ranking, however, did not change. Java is still on top, followed closely by Python — yet, it’s clear Python is on the rise. Javascript and C++ are neck and neck for third place, with Javascript only a few hundred postings ahead.


This year Java grew by around 6% compared to last January, which was right around 62,000 job postings at the time. Java is just about to celebrate its 24-year birthday, and as a programming language, it has definitely stood the test of time. Java was developed by a Canadian computer scientist that used to work with Sun Microsystems, James Gosling. It’s a language that lets developers “write once, run everywhere,” (WORA), which mean its compiled code, also known as bytecode, can run on almost any platform without recompilation.


Python was released more than a decade ago and was designed by Guido van Rossum, a Dutch programmer. It is a high-level programming language that is used as a ‘glue’ language to connect large existing software components. Also, its an object-oriented programming language that offer a vast collection of useful libraries and extension for developers and programmers.

Python is often described as simple and easy to learn, with a readable syntax that decreases the cost and time of program maintenance. This year, Python is skyrocketing with an increase of about 24% with 61,000 job postings compared to last year’s 46,000.


JavaScript is an object-based programming language created by an American technologist, Brendan Eich, and was inspired by Java. Unlike Java, JavaScript doesn’t create stand-alone apps or applets, it can only run on browsers and make them interactive. It can also change and update both HTML and CSS.

One of the advantages of using JavaScript is its speed. It runs immediately within the browser, and it also doesn’t need to be compiled on the client side. This year, JavaScript’s job posting didn’t change much at all, yet it’s still in the top three listings!


C++ was designed as an enhanced version of the C language by Bjarne Stroustrup, a Danish computer scientist. Its four-year development started way back in 1979 and was released in 1983. C++ is usually used for game development, drivers, client-server applications, system/application software, and embedded firmware. This year, C++ grew in popularity by 16.22% compared to last year with almost 37,000 job postings.


C# is a Microsoft programming language and is a hybrid of C++ and C languages. It lets developers build secure applications such as XML Web services, client-server, Windows client and database applications that run on the .NET Framework. C#’s job postings didn’t grow that much over the year, but it’s still one of the most popular languages.


PHP or Hypertext Preprocessor is created by Rasmus Lerdorf, a Danish-Canadian programmer. It’s an open source general-purpose scripting language for web development and can be embedded into HTML code from the server side execution. It’s commonly used to draw data out of a database on web pages. PHP’s job postings increased by 2,000 compared to last year.


PERL’s first appearance was in 1987, designed by an American computer programmer, Larry Wall. Wikipedia says it’s a “family of two high-level general-purpose, interpreted, dynamic programming languages, Perl 5 and Perl 6.” Perl’s popularity didn’t increase this year but is still one of the most popular programming languages to learn.

The Top Programming Languages

There are 256 known programming languages in the world. So TIOBE, a software quality company, made a list of the most popular programming languages which they update every month.

Below are the top 20 most popular programming languages as of February 2019.The 7 Most In-Demand Programming Languages of 2019 - Inner 2TIOBE calculates the rating of a programming language based on the number of hits on popular search engines such as Google, Youtube, Yahoo, Wikipedia, Amazon, Baidu, and Bing. They also consider the number of courses offered, third-party vendors and the number of skilled engineers worldwide.

One exciting prediction TIOBE made is that Kotlin, a statically typed, cross-platform, general-purpose programming language, currently at #31, can enter the top 20 because of its fast adoption in the industrial mobile app market. This prediction only shows that the tech industry is moving faster than it has ever been and if we don’t keep up, we would be left behind.

It’s important to note, however, that the list doesn’t show the best programming language there is. Its main aim is to help developers know whether their skill is up-to-date with their level of expertise and what programming language they can add to their skill set.

The key to becoming a successful developer is to have a never-ending desire to learn and grow. Mastering one programming language is commendable, but sometimes, it proves to be a liability as it becomes a developer’s limitation. Employers look for developers with different skills in programming who can be taught new languages quickly and skillfully. Therefore, learning a new programming language is imperative if you want to become a successful, full-fledged developer.

  3. Thanks for sharing this programing language with us, its very helpful for me to decide which programming I should learn. thanks and keep sharing.

  4. Well, I think this is a little misleading, since Node.js is very popular for creating servers and powers Google Cloud functions. We also have electron, which is used to create desktop apps, so the claim that Javascript only runs in the browser is false.

  5. I am so thankful for you.
    You clear all my doubts about latest programming best language.
    Thanks again

  6. hello
    The information which you provide is very much helpful for me. I recently completed my graduation and thinking of taking some programming Courses but I was so confused about which programming language should I learn. After going through your blog I can decide that Pursuing Python will be the best option for me as it is becoming popular each year and is expected to be in more demand in the upcoming future.
    I would be thankful to you if you can guide me if i am choosing the wrong Programming language.
