In collaboration with Nick Diakopoulos, an authority in data journalism, IEEE Spectrum gathered, scored, and combined 12 varying metrics from 10 respected sources, such as IEEE Xplore, Google, and GitHub. This is done with the purpose to identify and rank the most commonly utilized programming languages. Those who may hold diverse viewpoints on our weighting methodology, desire to explore more languages, or are eager to find the dominating language in any subdomain, for instance, mobile, are encouraged to try our online interactive version. This focused tool enables you to adjust the weight of each metric and stitch together your exclusive ranking.
Keep in mind that this study was originally executed in 2014, and with the ever-changing landscape of programming language popularity and use, more recent data may differ significantly. We suggest referring to the latest surveys for information that’s current.
This article was updated in 2025 to reflect current trends and insights.
