Introduction

Husk is a modern programming language that brings Rust's elegant syntax and powerful type system to the JavaScript ecosystem. Write code with familiar Rust patterns and compile to clean, readable ES modules that run on Node.js.

Why Husk?

• Rust-inspired syntax - Structs, enums, pattern matching, and Result types
• Strong static typing - Catch errors at compile time with algebraic data types
• JavaScript output - Generate clean ES modules with full npm ecosystem access
• First-class tooling - LSP support, VS Code extension, formatter, and watch mode

Quick Example

struct Person {
    name: String,
    age: i32,
}

fn greet(person: Person) -> String {
    format!("Hello, {}! You are {} years old.", person.name, person.age)
}

fn main() {
    let alice = Person { name: "Alice".to_string(), age: 30 };
    println!("{}", greet(alice));
}

This compiles to readable JavaScript:

const alice = { name: "Alice", age: 30 };
console.log(`Hello, ${alice.name}! You are ${alice.age} years old.`);
