Under the hood of Clojure repl execution

I understand Clojure code is compiled into classes and executed by JVM. For a Java project, I'm able to see a Jar gets created with .class files in it. But how exactly it works in case of a REPL?

Solution

  • Clojure code is compiled using the ASM library into class files. Those class files are loaded into a custom DynamicClassLoader.
