The 9 Most In-Demand Programming Languages of 2017

Do a simple web search and you’ll find there are hundreds of programming languages in existence. Do another search for the most popular ones and again, you’ll come up with a head-spinning list. To be as objective as possible, we’re examining the top programming languages from a career perspective.

There are many ways to rank programming languages, like the number of websites built with them, Google search results, GitHub projects or StackOverflow questions. We pored through data from job search engine Indeed.com for the number of job postings that contained the name of a programming language.

We did the same analysis for the top coding languages of 2016 and found some interesting changes in 2017, which are explained below. So without further ado, here are the nine most in-demand programming languages of 2017.

Indeed Job Postings

1. SQL

The number of Indeed job descriptions including SQL (Structured Query Language) increased by nearly 50,000 this year over last year, giving SQL a dramatic lead over the other languages. It’s unclear if this is entirely due to more SQL jobs in the market or a change in how Indeed works. Either way, SQL is still the clear leader in our analysis. SQL is used to communicate with and manipulate databases. It is extremely common, with many variations like MySQL and Microsoft SQL. Microsoft released SQL Server 2016 in the past year, which proved to be surprisingly popular and introduced several new features to make the language more open-source like integration with R, the popular data analysis programming language, and a Linux version.

 

2. Java

The number of Java positions available on Indeed went up by almost 30,000 in 2017 compared to 2016. This is possibly due to the rise in Android users in the market, the steady growth of its developer community, and some of the inherit characteristics of Java that make it worthwhile to learn. After all, Java is a simple, readable programming language used by millions of developers and billions of devices worldwide. All native Android apps are built in Java and 90 percent of Fortune 500 companies use Java as a server-side language for backend development. User have been getting excited about the upcoming Java 9 launch in July 2017, although Java Enterprise Edition declined in popularity in 2016.

 

3. Python

Python continued to grow in popularity in 2016 and moved up two places in our rankings to be the third-most common language by job posting. Furthermore, as highlighted in our most recent guide to learning Python, it’s also a general purpose programming language that emphasizes code readability and increasing developer productivity, used for desktop apps, web apps and data mining. In October 2016, Microsoft launched the beta version 2.0 of its Cognitive Toolkit open source deep-learning framework, which includes support for Python.

 

4. JavaScript

JavaScript (different from Java and mean stack development) moved down one place in our ranking compared to 2016, but otherwise the number of job postings stayed roughly the same. It’s a mainly client-side, dynamic scripting language used for front-end development. JavaScript is compatible across all browsers, used in over 90 percent of all web pages and is the most popular language on StackOverflow. Compatibility and adoption of JavaScript 6 continued to grow in 2016 and Progressive Web Apps became more usable, allowing offline-first functionality for web apps.

 

#5 C++

C++ grew by about 20,000 job postings over 2016 and passed pori to take fifth place. Built on C, the grandfather of all programming languages, C++ is a powerful, high-performance language used to build system software, games engines and desktop and web apps. Many beginners find C++ harder to learn than dynamically typed languages like Python or JavaScript.

 

6. C#

“C Sharp” saw a small increase in popularity in 2017, but not enough to keep it from falling behind C++. The language was developed for Microsoft’s .NET software framework and can now be used on non-Windows machines since the release of the new .NET Core open-source development platform in June 2016. Its main use is building Microsoft enterprise software. Most of the features in C# 7.0 were released last year, including language support for Tuples, local functions, pattern matching and many more.

7. Perl

Perl made a big jump in popularity this year to move ahead of iOS and PHP and knock Ruby off of our list. Perl, or “the duct tape that holds the Internet together,” as it’s been named, is actually two languages now; Perl 5 and Perl 6, which launched in Dec. 2015. Both of them are general-purpose dynamic programming languages that see a lot of use in CGI, graphics, network, and finance programming. Some think the growth of DevOps triggered this popularity surge because Perl is versatile and works well with other languages, making it a good DevOps tool.

 

8. iOS Family

Most developers writing for the iOS operating system use Objective-C, C, or Apple’s new Swift programming language. We counted any job postings that included “iOS” in our ranking and saw little change from 2016. Swift launched in 2014 and it rose quickly in popularity due to its scalability, speed, ease of use and strong demand from the mobile app marketplace. Apple released Swift 3.0 in Sept 2016 with new features including better translation of Objective-C APIs, modernizations of debugging identifiers and a new model for collections and indices. Apple plans to release Swift 3.1 and Swift 4 in 2017.

 

9. PHP

PHP stayed in the same place in our rankings from 2016 to 2017 with little change in popularity. It’s a server-side programming language used on more than 80 percent of websites today including Facebook, Wikipedia, Tumblr and WordPress. It wasn’t the buzziest language in 2016, but the sheer number of websites still built with it ensure it’s still a useful skill for developers, especially when paired with Javascript and SQL.

 

But Where’s Ruby?

Ruby on Rails, which was number nine on our list last year, dropped down several spots to number seventeen. This may be caused by Ruby losing some of its market share to increasingly popular alternatives like Node.js and Go. But that doesn’t mean there aren’t any jobs for it, or any reasons to learn Ruby on Rails in general. It’s still a popular language, just not as hot as it used to be.

If there’s one thing to take away from our analysis, it’s that no programming language can accomplish every task and the job market changes quickly from year to year. To be a successful developer, it’s important to master multiple languages and train yourself to pick up new languages quickly so you can adapt to changing job opportunities.

  1. Sql is often embedded in a programming language to interact with a database. Linux is not a language, it is an operating system. Oberon was an inreresting programming language which was an operating system at the same time. Formal language theory can be used to describe programming languages and you have special languages to program programming languages. C++ is the best.

  2. It really conflicts that few people say SQL is a programming language also and most of saying it is not? I am really confused about SQL but if it is worth to learn it I would like to go for it. For a good job is it wise decision to learn SQL and what other languages I should know with it.

  3. The people who think SQL is not a programming language need to look up the definition of programming language. I did.

  4. Hello world,

    I’m currently in my second semester of college for Computer Programming/Information Systems Technology. I’m extremely fucking excited and enjoying learning all the beginner shit right now. I’m so pumped for this.

    Is there anything you guys can tell me/recommend? What are the best jobs you can have and what languages are required? From what I gather, I’ll be learning Java, SQL, Python, Server-side, C# and VBP. I really want to create/write my own programs, I want to go for the BIG MONEY but also do something that is ENJOYABLE!

    Thanks in advance.

  5. i am from nigeria and i want to go for my masters in IT in canada or the US, does any1 have suggestions and quick facts?

  6. If it bothers you that SQL is considered a “programming language”, then you really need to get a life.

  7. Java will lose the only niche it has to Kotlin in the near future and will be obsolete Really now that Google is backing Kotlin and it is native on Android who wants to mess with Java. SQL is not a programming language it is a query language you can’t write a program in SQL and run it. Javascript is the hottest programming language for the years comming NO PROGRAMMING LANGUAGE can compete with it.

  8. i know a bit css html, and basics to adv of c, now i want to learn php, what program languages/scripts i need to learn more along with php?

  9. if i want to learn php, what more language to learn along with php? im justdone with basics to advance of c only.

  10. SQL programming language?? sadly yes… sql is turing complete
    but it is like try to plant a tree with a knife

  11. i want to learn LINUX. If i start to learn linux so its good for me or not. Anybody please guide me and explain me.

  12. Hello everybody, programming is very interesting. I am not a professional and have one question.
    How do the makers of programming languages program? In other words, what’s behind the language all the programmers are using?

    Thanks for explaining!
    Keep up the good programming,
    Justin

  13. Hi, i actually liked this but i want to know command on which language is going to be popular in future and learning which language can prove beneficial for me and the other thing learning which language can secure our future in financial ways.

    Regards

  14. I want to learn language which is recently used. what can i do for it. how i learn it and where from it please guide me.

  15. This page is really good .i gain a lot of information about languages and other .it’s really nice

  16. Hi, Nice article!!!!
    I am interested in learning SQL , N want to start my career with SQL. As I hv huge gap after my education. It’s about 4 year. Due to some reasons, I couldn’t start with it. So is it possible??? to start with sql? Or I need to learn something else… As I am from technical background, I hv some knowledge about programming. I am hesitating to start with it. It’s all bcz f ” 4 yr gap” . Plz help me

  17. its truly understandable abit i was confused about that software language java script and java,
    its now stacked

  18. For all those saying SQL is not a programming languaje, please check out 4GL programming languages and solve your doubts.

    SQL it is a Programming language, but it is not declarative it is just procedimental.

  19. To those that say that SQL is not a language, try to understand that under SQL umbrella there are T-SQL, P-SQL and so forth; all of them are considered programming languages, and at any rate, SQL in itself is both a DDL (Data Description Language) and a DML (Data Manipulation Language) and is a 4GL.

  20. Neither SQL or iOS are programming languages.

    SQL is a query language.
    iOS is an operating system. The main language used to program apps on iOS is swift.

    Javascript is the most popular language used on the Internet both on the server side and browser side. It’s a horrid language but super popular thanks to browsers and node.js.

    Go is gaining in popularity too and may even surpass C/C++ in the future.
    Java is only popular because of Android. But on the desktop it’s nearly dead. New projects tend not to use Java anymore because there are so many better choices available.

  21. i am student of b.tech 1st year from information technology branch. I want some idea about software language. I already learn c and java language. and now which language prefer

  22. ‘Ruby on Rails’ is a language? Last I checked, Ruby is a language, and Rails is a web framework written in Ruby. Admittedly, they are a tightly linked ecosystem. But I would have thought that at least someone claiming to dispense coding advice would understand the difference.

    And dudes, SQL _is_ a programming language. It’s domain-specific, and not Turing-complete, but you do actual programming with it.

  23. I just wanted to point out that there is no such thing as JavaScript 6 but it’s rather ES6 (short for EcmaScript 6) which is the committee that oversees the development of the language.

  24. Hi Jay,

    I am interested in learning a programming language to earn some part time money from home.

    Back in the day I did Fortran but that is about it.

    First of all, is that possible and are you saying SQL is probably the safe bet to start or another?

    Thank you!

  25. I’m sorry, but I can’t take seriously any article that treats SQL as a programming language.

  26. Whoever wrote this article is an idiot. SQL is the most popular term on Indeed because knowing SQL is ofter a requirement for Java, Python, PHP, Ruby developers. Knowing SQL alone will never get you a developer job.

  27. Nice article. If you are including SQL as programming language, include Assembly, Fortran,Ada,Prolog also.

  28. I would be very interested in seeing the full list from you analysis. Do you publish the full list of popular programming languages?

  29. This site is awesome!!!!
    It had a great say on each language and it was a good read.
    The only thing is i dont like they way they analyse.

  30. did your research for the demand for JavaScript also include the dozens of libraries that are built on JavaScript?

  31. I don’t intend to be rude but it’s really grinding my gears so I’m going to mention it…

    SQL isn’t a programming language.

    I’ll get my coat.
