firescript is a statically and strongly typed programming language that compiles natively or to JavaScript + Wasm. It is designed to be simple, powerful, and easy to learn while remaining expressive for advanced applications.

Disclaimer: firescript is currently in development and is not yet feature-complete. The language and compiler are subject to change. Not everything described in this document is implemented or working. Current builds may leak resources; the design goal is deterministic destruction via an ownership model.

• Static & Strong Typing: Enhances code readability and reliability.
• Simple Syntax: Combines the best of C, Java, JavaScript, and Python.
• Everything is Explicit: No implicit conversions or hidden behavior.
• Versatile Compilation: Supports native binaries and JavaScript output.
• Cohesive Design: All parts of the language work seamlessly together.
• Deterministic Ownership Model (planned): Ownership, moves, borrows, and explicit cloning instead of a tracing garbage collector. See the Memory Management Model.

// Define a function that returns the nth Fibonacci number int8 fibonacci(int8 n) { if n <= 1 { return n } return fibonacci(n - 1) + fibonacci(n - 2) } // Print the first 10 Fibonacci numbers for (int8 i : range(9)) { print(fibonacci(i)) } 

Algorithm pseudo‑code:

function fibonacci(n) { if n <= 1 { return n } return fibonacci(n - 1) + fibonacci(n - 2) } fibonacci(47) 

Fibonacci of 47 is used to provide a reasonable runtime for comparison. Test is run 5 times and the average time is reported. Tests are run on an AMD Ryzen 7 5800H processor.

• C Compiler (GCC recommended, but any C compiler should work as long as its location is in the CC environment variable)
• Python 3

# Debian/Ubuntu sudo apt-get install gcc python3 libgmp-dev libmpfr-dev # Fedora/RHEL/CentOS sudo dnf install gcc python3 gmp-devel mpfr-devel # Arch/Manjaro sudo pacman -S gcc python3 gmp mpfr # Clone the repository git clone https://github.com/alec-jensen/firescript.git cd firescript

# Compile a firescript program python3 firescript/firescript.py program.fire # Execute the compiled program ./output/program
