Hi, Developing with cursive for almost half a year now, I still do use Lighttable (http://lighttable.com/) a lot. I find it especially useful for learning clojure as it delivers the most instant feedback I can think of by giving back results directly in the editor. So go and give it a shot, as

The REPL takes some effort if you're not used to it, but stick with it and you shall be greatly rewarded! Since it's such an interactive workflow, I feel that it helps to view someone else use it. There's a great intro to Clojure video by Chas Emerick where he develops a small web application,

I find these examples very memorable. Despite the doc strings clearly stating the differences between transduce and reduce, one can still hastily assume that transducing [0 1 2] will have 0 as the init argument. I will add that the culprit is in defining the +ten's arguments with [& args] form,

There is a big shift in mindset when switching to REPL-based development. Essentially, with the Java workflow you describe, you are thinking of launching and testing your whole application as a single unit. What the REPL will let you do, which might not be immediately obvious depending on your bac

Reducing functions have three arities: 0-arity: returns the initial state 1-arity: handles completion 2-arity: reduce step function Using arities to denote different functionality is a little odd, but it does make sense for functions like addition and conjoin: (+) => 0 (+ 1) => 1 (+
