Random guitar strum pattern generator for practice.
Check it out: vilda.net/s/rsp.
It should look as follows: 
It also contains an initial Python version random_strum_pattern.py after which I decided I could make it a small website with a bunch of buttons.
The current version works for me. It took me an hour to build and I'm satisfied with this yield/investment ratio. Therefore, please do not send me bug/feature requests. If you however want to contribute, I can review & accept pull requests.
The code is written in TypeScript+Node+Webpack. Run/compile as follows:
npm install
npm run build # or `npm run dev` for local server
