What Clojure library have you enjoyed working with the most?

  • Tufte has helped us understand inefficient areas of our code to drive performance improvements.

  • Switching from Spring to Mount has made managing app state much easier and more testable.

  • Slingshot enables clojure-centric exception handling.

  • clj-time is non-glamourous, but an extremely useful utility library.

What about working with Clojure gives you the most value?

Persistent data structures reduce cognitive load and eliminate an entire class of errors caused by mutation. REPL-driven development provides immediate feedback and is more enjoyable, helping us rapidly deliver features to customers. Java interop lets us leverage existing libraries and benefit from the maturity of the JVM. The standard library is built around simple, powerful, and composable data manipulation functions. Overall, Clojure makes our code more enjoyable to write, pleasant to read, and easier to review.
