# node-polyglot-fibonacci

An experiment in writing node.js bindings to other languages.

The bindings are to a function that calculates the Nth Fibonacci term.

## Implementations

* [C++](./lib/fibonacci.cc) - [bindings](./lib/fibonacci-cc.js) via [node-gyp](https://github.com/TooTallNate/node-gyp)

    - recursive

    - #TODO: recursive memoized

    - iterative

* [JavaScript](../lib/fibonacci-js.js)

    - recursive

    - #TODO: recursive memoized

    - iterative

* #TODO

    - Rust - [example](https://github.com/alexcrichton/rust-ffi-examples/tree/master/node-to-rust/src)

    - C++ via node-ffi. [example](https://github.com/node-ffi/node-ffi/blob/master/example/factorial/factorial.c) 

## Use it

```

⚡ FIBONACCI_IMPL=lib/fibonacci-cc.js node index.js 42

433494437

```

```

⚡ FIBONACCI_IMPL=lib/fibonacci-js.js node index.js 42

433494437

```

## Compare Implementations

```

⚡ make compare N=42

node bin/compare.js
