 Prior to Svelte 5, stores were the go-to solution for creating cross-component reactive states or extracting logic. With runes, these use cases have greatly diminished.

 Stores are still a good solution when you have complex asynchronous data streams or it's important to have more manual control over updating values or listening to changes. If you're familiar with RxJs and want to reuse that knowledge, the `$` also comes in handy for you.
