The entire syntax for Clojure fits in a single line. Its easier to learn and being as expressive as it is, the core idioms are quickly picked up as well.
So - You can get into it quickly, very quickly if you're already familiar with FP.
The brevity of the code means that you'll produce much more robust code, which takes up a lot less screen real-estate. This allows you to grasp the functionality of any code you read, very quickly and start working on the problem.
It'll go as fast as Java, but slower than C/Rust. For some performance oriented tasks, you'll have to put in more work than makes sense, to get the performance you want. But for 99% of the Apps that are being written, Clojure will perform just fine and you'll end up with better code.
Compared to Haskell or most other FPs (not F#) you get the added benefit of being on the JVM. Write once, run everywhere. Huge libs to do everything from 3d graphics to webserving.
In most cases, I use Clojure for the above reasons summed up in this one sentence: I makes me more effective than the alternative.
ps: Having enjoyed Lisps for 20 years or so, Ive never used Par-Edit :)
There’s a balance to be struck between conciseness and readability. Don’t be terse as APL and don’t be as verbose as Java. Clojure hits the sweet spot for me, it’s subjective ofc.
I disliked the syntax, but was very curious why lots of devs were fascinated by it. Started to study Lisp/Clojure in 2015 and used more and more, and nowadays I love it.
I use Clojure because I find it more more fun and interesting to program in. As a bonus, it happens to also be practical, robust, productive and safe; with great tooling, a huge ecosystem, reach to the browser, server, command line, and desktop/mobile, good performance, good scale, and an awesome community.
