The most popular software languages used to create projects on GitHub are JavaScript, followed by Java, with tremendous growth in new projects starting around 2012. The most popular open source licenses used for these projects are MIT and Apache 2.0, with BSD and GPL licenses following behind. A specific analysis of the Golang language shows that nearly three times as many projects use the Apache 2.0 license compared to MIT, likely due to companies wanting to enforce their trademarks. The study also reveals some interesting outliers, such as the University of Illinois - NCSA Open Source License being used by only two projects.
