-Here is an [interesting discussion](https://www.reddit.com/r/vuejs/comments/18fnilj/why_to_use_pinia_instead_of_global_refs/) about it on */r/vuejs*. [Code example](https://github.com/jellyfin/jellyfin-vue/blob/master/frontend/src/store/clientSettings.ts#L98) from Reddit user **@ferferga** shows how to use TypeScript classes with private modifiers, getters, setters (no *.value*) and first class type support as composable stores (which would be impossible with Pinia). Using TS classes here might not be a good practice but demonstrates flexibility and power of the Composition API.
