What is Quanta

Quanta is a modern JavaScript engine designed for the Solar Project with a focus on modular architecture and high performance. Built from the ground up in C++17, Quanta provides:

Core Features

• Modular Architecture - Clean separation of concerns with 15+ focused modules
• High Performance - Optimized execution with advanced compilation techniques
• Production Ready - Comprehensive test coverage with 100% success rate
• Cross Platform - Windows, Linux, and macOS support

JavaScript Support

• ES6+ Compatibility - Modern JavaScript features
• Complete Built-ins - Math, String, Array, Object, JSON, Date
• Advanced Operations - Nested objects, complex arrays, functional programming

---

ECMAScript Compatibility

Quanta has been tested against the official Test262 ECMAScript test suite (51,216 tests). Results demonstrate strong foundational JavaScript support with ongoing development for advanced features.

For Developers

Building Quanta

Prerequisites

• C++17 compatible compiler (GCC/Clang/MSVC)
• Make build system
• Windows/Linux/macOS support

Build Instructions

Unix like Systems (Linux/macOS)

# Clean build with parallel compilation
make clean && make -j4

# Debug build
make debug

# Release build (default)
make

Unix systems can build Quanta smoothly with standard development tools.

Windows For Windows development, MSYS2 is required for compilation. Native Windows builds have not been tested yet. Binaries built with MSYS2 do not carry any GNU dependencies and run natively on Windows.

1. Install MSYS2 from https://www.msys2.org/
2. Install required packages:

   pacman -S mingw-w64-x86_64-gcc mingw-w64-x86_64-make

3. Build using standard commands in MSYS2 terminal

Build Outputs

• build/bin/quanta - Main JavaScript executable (3.2MB)
• build/libquanta.a - Static library (4.9MB)

Testing

Run Test Suite

# Execute JavaScript code directly
./build/bin/quanta -c "console.log('Hello World');"

# Execute JavaScript file
./build/bin/quanta example_file.js

# Interactive REPL
./build/bin/quanta
