This repository is used for the course "How to implement a dynamic language on the JVM" at University Gustave Eiffel (Paris France)

This repository provides the basis to implement your own

• Abstract Syntax Tree Interpreter
• Stack-based Interpreter
• Java Virtual-Machine-based Interpreter

of a dynamically typed language named smalljs which is almost a subset of JavaScript.

run Maven with a Java 25

  mvn package

a jar named smalljs-2.0.jar in the folder target is generated

Still with Java 25

  java -jar target/smalljs-2.0.jar ast samples/hello.js
  java -jar target/smalljs-2.0.jar stack samples/hello.js
  java -jar target/smalljs-2.0.jar jvm samples/hello.js

with 'ast' being the AST interpreter, 'stack' being the Stack-based interpreter and 'jvm' being the JVM-based interpreter.
