Every year, Stack Overflow surveys tens of thousands of developers around the world to understand how they work, what technologies they use and some other fun facts. The complete report is packed with overwhelming amounts of data that offers something for everybody.
Blockchain is one tech trend the world loves to follow these days and Stack Overflow asked developers their opinions on it. The technology has been making headlines for the last few years but still not necessarily finding its place in the mainstream. The results saw that 80% of organizations are not using Blockchain at all and developers have mixed reviews on how it can be used in the future. Sure, two-thirds of the respondents said Blockchain can be useful in various aspects, but 16.8% say it is a passing fad and 15.6% believe that Blockchain is an irresponsible use of resources.
Expectedly, as they do every year, Stack Overflow used the opportunity to learn about the most popular, loved, hated and wanted technologies. The charts are long and filled with data, so we summarized the findings in the tables below:
For the first time this year, Stack Overflow asked about frameworks for the web separately from other frameworks and libraries. jQuery is the most broadly used. It's also interesting to note that the results in the tables only represent responses by professional developers and when all developers were surveyed, React.js actually ranked higher than Angular.js in popularity.
Although they didn't make the top 5, more developers did say they use the deep learning framework TensorFlow more than Torch/PyTorch. Interestingly, Torch/PyTorch is more loved than TensorFlow, but TensorFlow is one of the "Most Wanted" (developers who do not yet use it but say they want to learn it).
As expected, MySQL remains the most popular database used among developers and, for the third year in a row, Redis took the top spot in the Most Loved category and MongoDB clinched #1 in Most Wanted.
New this year, Stack Overflow asked developers about container technologies and Docker turned out to be the third most broadly used platform, second most loved and first most wanted.
When it comes to Developer environments, it's clear that Visual Studio Code takes the cake, specifically among Web Developers, DevOps and SREs. It ranks the second most popular among Mobile Developers, who are slightly more likely to choose Android Studio.
The survey report contains loads more information around technology trends and predictions by developers. Some are obvious (more developers use Windows as their primary operating systems), some facts are fun but useless (30% believe Elon Musk will be this year's most influential person in tech) and some are super detailed (you can dive much deeper into the stats summarized in the tables above).
