Developers – What job should you chase in 2020?

As a developer you may be thinking, What should I concentrate my learning on in 2020?

With over 2000 programming languages being created since the software was born, many have gained substantial popularity over others.

As we advance to 2020, it’s a good time to reflect on learning priorities for 2020. 

But before we start talking about Programming Languages let me clarify:

  • I’m not arguing that any language is objectively better than any other.

Most popular programming languages

GitHub is one of the largest code repositories in use today. Every year they create a Year in Review report, sharing statistics about their programmer community.

Of course, all of these insights are up for debate, but they are worth considering if you want to stay ahead of the curve.

Below are the most popular programming languages of 2019


According to Tiobe, Java has been the number 1 or 2 most popular language basically since its creation in the mid-90s. Many of the world’s biggest companies use Java to build desktop apps and backend web systems.

If you know Java, chances are you won’t be desperate for work!


C is one of the oldest, most popular programming languages, thanks to its near universal portability and early adoption by Tech’s biggest brands, including Microsoft, Apple, Linux, and Oracle.

Nearly everything that we touch today, from our cell phones to alarm clocks, is influenced by—if not directly written in—the C language


The popularity of Python has risen steadily over the past 15 years, finally breaking the top 5 on the Tiobe Index a few years ago. This is because Python is a major language in some of the most exciting technologies today.

Machine learning, artificial intelligence (AI), Big Data, and Robotics all rely heavily on Python (Robotics also relies on C for its use in systems programming). Cyber Security, one of the top software challenges of our time, is also driven by Python.

What is the highest paid?


The Go language was developed by Google and introduced in November 2009. Being an open source platform, it is actively used for projects within the corporation and a number of well-known world-class services (SoundCloud, Netflix, Dropbox).

In the past few years, the popularity of Go has grown dramatically thanks to advantages for multi-threaded tasks such as efficient processing of parallel processes, fast start-up time and using memory only when it is really necessary. Many consider it to be the server language of the future.


Python and JavaScript are hot in the startup world. Many startups use Django (Python), Flask (Python), and NodeJS (JavaScript) as their backend frameworks. Python and JavaScript are easy-to-learn and therefore considered the best programming languages to learn for beginners. Moreover, both of them also provide a huge market opportunity. Therefore, those who are looking for a job change may also consider learning them.
