Yarn Test

Just me playing around to understand Yarn a bit

Notes

.gitignore
yarn set version stable locks the yarn version used by this project to the latest stable version (docs)
From recipes
- yarn add --dev typescript add typescript (docs)
- yarn dlx @yarnpkg/sdks vscode adding VSCode integration (Editor SDKs & dlx docs)
- yarn plugin import typescript enable Yarn's TypeScript plugin, which helps manage @types/* dependencies automatically (docs)
- After adding an app.ts file it can be compiled with yarn tsc app.ts and the resulting json run with node app.js
- I still do not understand what is meant by dependencies in yarn and how to use them
