REPL Driven Mobile Development with Clojure(script)
This document discusses REPL driven mobile development using ClojureScript. It begins by introducing REPL (Read-Eval-Print Loop) as an interactive programming environment. The document then discusses ClojureScript and how it compiles Clojure code to JavaScript, enabling mobile development. Key benefits of the REPL driven approach using ClojureScript discussed are immediate feedback, incremental development, and better debuggability. CLJSrn is introduced as a framework for building native mobile apps using ClojureScript and React. Examples are provided of REPL driven development in ClojureScript.
