Juno

Familiar C-like Syntax

Juno brings the simplicity and clarity of C to the JVM. If you know C, you'll feel right at home with Juno's straightforward syntax and modern features.

import Io;

void main() {
  Io.println("Hello, Juno!");
}

Variant Types

Juno supports variant types (union types) allowing a variable to hold values of different types. Write flexible, type-safe code without complex inheritance hierarchies.

import Io;

void main() {
  string|int x = 42;  // x is an integer
  x = "hello";           // now x is a string
  Io.println(x);
}

Simple Tooling

Juno's compiler is straightforward and intuitive. Build, run, and compile to JVM bytecode with simple commands. No complex build systems required.

$ juno run hello.juno
Hello, Juno!

$ juno build program.juno
$ java program
