We're excited to announce the release of Super.js 0.2.0! This release brings significant enhancements to the type system, compiler performance, and developer tooling.

🚀 What's New in 0.2.0​

Enhanced Type System​

Advanced Generic Constraints​

Super.js now supports more sophisticated generic constraints, allowing for better type safety in complex scenarios:

// Enhanced generic constraints
interface Lengthwise {
  length: number;
}

function loggingIdentity<T extends Lengthwise>(arg: T): T {
  console.log(arg.length);
  return arg;
}

// Multiple constraints
interface HasId {
  id: number;
}

interface HasName {
  name: string;
}

function processEntity<T extends HasId & HasName>(entity: T): void {
  console.log(`Processing ${entity.name} with ID ${entity.id}`);
}

Conditional Types​

Support for conditional types enables powerful type-level programming:

type NonNullable<T> = T extends null | undefined ? never : T;
type ReturnType<T> = T extends (...args: any[]) => infer R ? R : any;

// Complex conditional types
type TypeName<T> = T extends string
  ? "string"
  : T extends number
  ? "number"
  : T extends boolean
  ? "boolean"
  : "object";

Mapped Types​

Create new types by transforming existing ones:

interface User {
  id: number;
  name: string;
  email: string;
}

// Make all properties optional
type PartialUser = Partial<User>;

// Make all properties read-only
type ReadonlyUser = Readonly<User>;

// Pick specific properties
type UserBasic = Pick<User, "name" | "email">;

Compiler Improvements​

Source Map Generation​

Full source map support for better debugging experience:

superjs build --source file.sjs --sourcemap

Incremental Compilation​

Faster rebuilds for large projects:

superjs build --incremental

Parallel Compilation​

Utilize multiple CPU cores for faster compilation:

superjs build --parallel

Enhanced Tooling​

Advanced Linting Rules​

New linting rules for better code quality:

# Enable strict rules
superjs lint --rules strict

# Custom rule configuration
superjs lint --config .superjsrc

Test Coverage Reporting​

Built-in test coverage with detailed reports:

superjs test --coverage --threshold 80

Performance Profiling​

Identify performance bottlenecks in your code:

superjs build --profile

Language Features​

Decorator Support (Experimental)​

Decorators for class and method enhancement:

function log(target: any, propertyKey: string, descriptor: PropertyDescriptor) {
  const method = descriptor.value;
  
  descriptor.value = function (...args: any[]) {
    console.log(`Calling ${propertyKey} with args:`, args);
    const result = method.apply(this, args);
    console.log(`${propertyKey} returned:`, result);
    return result;
  };
}

class Calculator {
  @log
  add(a: number, b: number): number {
    return a + b;
  }
}

Template Literal Types​

Type-safe template literal manipulation:

type EventType = "click" | "hover" | "focus";
type HandlerName<T extends EventType> = `on${Capitalize<T>}`;

function createHandler<T extends EventType>(event: T): HandlerName<T> {
  return `on${event.charAt(0).toUpperCase() + event.slice(1)}` as HandlerName<T>;
}

const clickHandler = createHandler("click"); // "onClick"

🔧 Breaking Changes​

Generic Constraint Syntax​

The generic constraint syntax has been updated for better consistency:

// Old syntax (deprecated)
function process<T extends HasId>(item: T): void {}

// New syntax
function process<T extends HasId>(item: T): void {}

Decorator Implementation​

Decorator behavior has been standardized:

// Updated decorator signature
function decorator(target: any, propertyKey: string, descriptor: PropertyDescriptor) {
  // Implementation
}

📈 Performance Improvements​

• Type checking: 40% faster for large codebases
• Compilation: 60% improvement with parallel compilation
• Memory usage: 30% reduction in memory consumption
• Startup time: 50% faster CLI startup

🛠️ Migration Guide​

Upgrading from 0.1.0​

1. Update Super.js:

   npm install -g superjs@latest
   

2. Review Generic Constraints: Check your generic constraints for the new syntax requirements.

3. Test Decorators: If using decorators, review their implementation for compatibility.

4. Update Configuration: Review your .superjsrc configuration for new options.

New Configuration Options​

{
  "compiler": {
    "incremental": true,
    "parallel": true,
    "sourcemap": true
  },
  "test": {
    "coverage": {
      "enabled": true,
      "threshold": 80
    }
  }
}

🎯 What's Next​

Planned for 0.3.0​

• Higher-kinded types
• Dependent types
• Advanced pattern matching
• Enhanced IDE support

Thank you for being part of the Super.js community! 🎉

We're excited to announce Super.js, a strict, clean, and efficient superset of JavaScript that enforces ECMA standards with built-in type safety, formatting, linting, and testing capabilities.

What is Super.js?​

Super.js extends JavaScript with static type checking while maintaining pure JavaScript semantics. It provides TypeScript-like type safety with a focus on ECMA compliance and zero-configuration development experience.

Key Features​

• Type Safety: Static type checking with JavaScript-first approach
• Type Inference: Smart type inference based on ECMA standard patterns
• Built-in Tooling: Integrated formatter, linter, and testing framework
• Universal Compilation: Supports both frontend and backend environments
• Zero Configuration: Works out of the box with sensible defaults
• Fast Compilation: Optimized compilation process for quick development cycles
• JavaScript Version Selection: Target specific JavaScript versions (ES5 to ES2022)
• Native JSX Support: First-class JSX syntax support without external dependencies

Why Super.js?​

JavaScript has evolved significantly over the years, but many developers still struggle with:

1. Type Safety: Runtime errors that could be caught at compile time
2. Tooling Fragmentation: Multiple tools for formatting, linting, and testing
3. Configuration Overhead: Complex setup processes for new projects
4. ECMA Compliance: Ensuring code follows standards without additional features

Super.js addresses these challenges by providing:

• Unified Tooling: One tool for compilation, formatting, linting, and testing
• Zero Configuration: Sensible defaults that work out of the box
• ECMA Compliance: Strict adherence to JavaScript standards
• Type Safety: Catch errors before they reach production

Getting Started​

Installation​

npm install -g superjs

Your First Super.js File​

Create a file with the .sjs extension:

// hello.sjs
function greet(name: string): string {
  return `Hello, ${name}!`;
}

const message = greet("World");
console.log(message);

Compiling and Running​

# Compile the file
superjs build --source hello.sjs

# Run the compiled JavaScript
node hello.js

Language Features​

Type Annotations​

interface User {
  id: number;
  name: string;
  email: string;
  age?: number; // Optional property
}

class UserAccount {
  constructor(public user: User) {}
  
  updateEmail(newEmail: string): void {
    this.user.email = newEmail;
  }
}

Type Inference​

// Super.js automatically infers types
const numbers = [1, 2, 3]; // number[]
const user = {
  name: "John",
  age: 30
}; // { name: string, age: number }

Generics​

function identity<T>(arg: T): T {
  return arg;
}

class Stack<T> {
  private items: T[] = [];
  
  push(item: T): void {
    this.items.push(item);
  }
  
  pop(): T | undefined {
    return this.items.pop();
  }
}

Built-in Tooling​

Formatter​

# Format your code
superjs format file.sjs

Linter​

# Lint your code
superjs lint file.sjs

Testing​

// math.test.sjs
import { describe, it, expect } from 'superjs/test';
import { add } from './math.sjs';

describe('Math functions', () => {
  it('should add two numbers correctly', () => {
    expect(add(2, 3)).toBe(5);
  });
});

# Run tests
superjs test

JavaScript Version Targeting​

Super.js supports targeting specific JavaScript versions:

# Target ES5 (for older browsers)
superjs build --source file.sjs --target es5

# Target ES2020
superjs build --source file.sjs --target es2020

# Default (ES2022)
superjs build --source file.sjs

Project Structure​

The Super.js project consists of multiple implementations:

• prototype/: TypeScript implementation with full feature set
• compiler/: JavaScript implementation focusing on core compiler features
• llvm/: C++ implementation using LLVM for high performance
• examples/: Comprehensive examples and use cases
• docs/: Project documentation (this site)

What's Next?​

We're actively developing Super.js and have an exciting roadmap ahead:

1. Enhanced Type System: Advanced type features and better inference
2. Performance Optimizations: Faster compilation and better runtime performance
3. IDE Integration: Better editor support and developer experience
4. Ecosystem Tools: Package manager, dependency management, and more
5. Community: Documentation, examples, and community contributions
