jank is a general-purpose programming language which embraces the interactive, value-oriented nature of Clojure as well as the desire for native compilation and minimal runtimes. jank is strongly compatible with Clojure and considers itself a dialect of Clojure. Please note that jank is under heavy development; assume all features are planned or incomplete.
Where jank differs from Clojure JVM is that its host is C++ on top of an LLVM-based JIT. This allows jank to offer the same benefits of REPL-based development while being able to seamlessly reach into the native world and compete seriously with JVM's performance.
Still, jank is a Clojure dialect and thus includes its code-as-data philosophy and powerful macro system. jank remains a functional-first language which builds upon Clojure's rich set of persistent, immutable data structures. When mutability is needed, jank offers a software transaction memory and reactive agent system to ensure clean and correct multi-threaded designs.
nREPL is a Clojure network REPL that provides a REPL server and client, along with some common APIs of use to IDEs and other tools that may need to evaluate Clojure code in remote environments.
Calva is an integrated, REPL powered, development environment for enjoyable and productive Clojure and ClojureScript programming in Visual Studio Code. It is feature rich and turnkey. A lot of effort has been put into making Calva a good choice if you are new to Clojure. Calva is open source and free to use.
