“Clojure is a “robust, practical and fast programming language” whose original design goals were aimed at giving developers “succinctness, flexibility and productivity”. It turns out that most organizations today are interested in achieving those very goals – as the landscape evolves, they need technologies that help them move faster, respond more effectively, and to take advantage of new architectures and infrastructure. In short, they need simple tools that help them be more agile.

In this, the sixth consecutive year of the State of Clojure survey, we are seeing the evidence that Clojure is moving across the chasm from a niche tool used by explorers and hobbyists to becoming a critical part of the commercial development landscape, and that its adoption is spreading both broadly among companies, but also more deeply within them.

Before we get to the results, we’d like to first thank everyone who took the time to respond to the survey this year. Response was up more than 75% this year, with 2,445 total responses to analyze. This kind of data is invaluable to the people and organizations using (or considering) Clojure today. As always, we’d also like to thank Chas Emerick for starting the survey back in 2010…”
