How to play:

• Come up with a code (and optionally mark it down at the bottom by selecting your colors and placing them in the slots)
• Press next to get the next guess
• Mark the amount of red and white pegs next to the computer's guess
• Repeat!

It's guaranteed to guess your code within 5 guesses.

Why WebAssembly?

As a start, I implemented this algorithm with a naive approach in JavaScript and it was far too slow to be playable, taking several seconds between guesses.

I really enjoy using Rust, and since it has built-in support for compiling to WebAssembly and a mature ecosystem of libraries and utilities designed for WebAssembly, I figured I would implement the performance-sensitive parts in Rust.

Run locally

Build the WASM package

wasm-pack build

Test the algorithm

cargo test

Webpack test server

cd webpack
npm install
npm run dev
