Top Programming Languages 2021
This app ranks the popularity of dozens of programming languages. You can filter them by excluding sectors that aren't relevant to you, such as "Web" or "Embedded." (The sectors that languages are assigned to are based on typical use patterns we've seen in the wild, rather than atypical or proof-of-concept projects.)
Rankings are created by weighting and combining 11 metrics from eight sources: CareerBuilder, GitHub, Google, Hacker News, the IEEE, Reddit, Stack Overflow, and Twitter. (Read more about our method and sources.) Special thanks to CareerBuilder for letting us use its data.
The default set of weights produces our IEEE Spectrum ranking, but there are preset weights for those more interested in what's trending or most looked for by employers. Don't like the presets? Make your own ranking by adjusting the weights yourself using the "Create Custom Ranking" option.
About Top Programming Languages
Created by senior editor Stephen Cass, Top Programming Languages is one of IEEE Spectrum 's most popular interactives. A new edition with updated data and rankings is released every year. The 2021 edition was created by Cass, Preeti Kulkarni, and Erico Guizzo, based on an original design by Nick Diakopoulous.
