G1Joshi Clojure
A Lisp hosted on the JVM (and JS via ClojureScript) with a focus on immutability.
When to Use
- Data processing
- Concurrency (Software Transactional Memory)
- Web development
- JVM interop needed
Quick Start
(println "Hello, World!")
(defn square [x]
(* x x))
(map square [1 2 3]) ; (1 4 9)
Core Concepts
Persistent Data Structures
Immutable lists, vectors, maps, and sets that structurally share data to be efficient.
REPL Driven Development
Writing code interactively in a Running Eval-Print Loop.
Macros
Code that takes code as input and returns code.
Best Practices
Do:
- Use the REPL
- Use threading macros
->and->>to make code readable - Leverage JVM libraries
Don't:
- Use atoms/agents/refs unless you need mutable state
- Write deeply nested parentheses (use structural editing)
