This is an implementation of Conway's Game of Life written in Elm.
It renders a resizeable playing board whose state can be evolved by clicking the button.
Individual cells can be toggled dead or alive by clicking them.
You'll need Elm installed to build this.
There is no special build tooling. The Elm compiler is used to spit out a .js file.
elm make src/Main.elm --output=main.js
The html is static and expects a main.js to exist in its directory. The files can then be served by any http server.
There is a build script that will compile and copy the relevent files into a build directory. Just run ./build.sh and point your webserver at build/.
