Typescript Tic-Tac-Toe demo
It's already built in Javascript, so you don't need to use Typescript at all to see it work.
But if you want to make changes, make sure Typescript is installed.
npm install -g typescript (might require sudo)
Build the node modules with npm install
Then you work in src/index.ts, and use tsc to build to dist/index.js.
Hint: use tsc -w to watch for changes and auto-build.
Then in another terminal, launch lite-server (part of the package) with npm start. This will also auto-reload.
