Global Popular Programming Languages: Insights from TIOBE, PYPL, StackOverflow, GitHub, and More

We all know that C++, MATLAB, and Java have long been favored in technical schools, with many graduates eager to learn them, but are they truly what the industry needs? To answer this, we consulted reputable language index sites and scraped data from global job portals such as Indeed and Glassdoor, aiming to identify the world’s most popular languages and the ones most demanded by employers.

Note: Ranking language popularity is not intended to declare any language superior or inferior; rather, it seeks to reveal which languages users prefer and which are most needed by the industry.

TIOBE Index

The TIOBE Programming Community Index, created and maintained by the Dutch company TIOBE, ranks languages based on the number of search engine queries for each language keyword. Because TIOBE only indexes Turing‑complete languages, SQL and HTML are excluded. The November 2016 ranking showed Java still at the top, followed closely by C and C++. Notably, Visual Basic and Python jumped significantly, overtaking JavaScript, and even assembly language entered the top ten.

PYPL

The PYPL (PopularitY of Programming Language) index measures the frequency of language tutorial searches on Google. It confirms Java as the clear winner; Python rose 6.8% over the previous five years, while PHP fell 5.0%.

Professor Adrian Runceanu from Constantin Brâncuși University, with over 16 years of experience in C++, Java, and Oracle, explains why C++ remains in the top ten: “C/C++ provides a solid mechanism for creating portable applications and is easy to learn, making it popular among students. Languages such as JavaScript, Java, and Python are better suited for web development. I believe C/C++ will retain a dominant position in the coming years.”

StackOverflow

Stack Overflow, a Q&A platform with over 4 million users and more than 10 million questions, shows JavaScript as the most frequently used language among its questions, while PHP’s ranking has slipped compared to Node and Angular.

GitHub

Before its September 2016 annual conference, GitHub released a statistical report. In the past 12 months, GitHub had over 5.8 million active users and more than 19.4 million active repositories. Its language ranking places JavaScript at the top, unsurprisingly, but its rapid surge over competitors is noteworthy.

HackerEarth

HackerEarth offers monthly coding challenges and hiring opportunities, supporting more than 30 programming languages. With over one million registered programmers, the platform reveals the languages they prefer most.

Indeed

Indeed, one of the highest‑traffic job sites in the United States, operates in over 50 countries and supports 28 languages. According to its usage ranking, Java is the most sought‑after language, followed by JavaScript, PHP, and C, with a surprising rise in demand for R.

Professor Deepak Garg, an expert in data mining and chair of the IEEE Computer Society India Council, observes that “the core set of tools and applications in the computing industry is bridging gaps, leading to an evolution in language complexity. Languages are becoming higher‑level, allowing programmers to focus more on logic and application rather than low‑level data structures and syntax.”

Glassdoor

Glassdoor enables employees to review organizations. Its developer job listings show that Java developers are most needed, followed by JavaScript. R and C++ also rank highly, while demand for Python and Perl is on the rise.

Languages Expected to Grow in 2017

Observing these trends, Java and JavaScript will likely remain the most popular languages for web development, while Google’s Go continues its ascent. Ruby stays favored by startups. Data analysis suggests Mozilla’s Rust and Facebook’s Hack could break into the top ranks in the second half of 2017.

Languages projected to rise in 2017 include:

R – Growing demand for statistical analysis and data science makes R a strong contender.

MATLAB – As mathematicians and scientists rely more on it for analysis, MATLAB’s role will expand.

SQL – With the exponential growth of database usage, SQL remains essential.

Arduino – Combining C and C++, Arduino is poised to become a key skill for embedded development.

Swift – Apple’s push to replace Objective‑C with Swift promises a rapidly expanding market.

These predictions are speculative, and only time will reveal which programming languages truly dominate in 2017.
