 An animation is triggered when the contents of a [keyed each block](each#Keyed-each-blocks) are re-ordered. Animations do not run when an element is added or removed, only when the index of an existing data item within the each block changes. Animate directives must be on an element that is an _immediate_ child of a keyed each block.
 
 Animations can be used with Svelte's [built-in animation functions](svelte-animate) or [custom animation functions](#Custom-animation-functions).

 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.
 
 - when extracting logic, it's better to take advantage of runes' universal reactivity: You can use runes outside the top level of components and even place them into JavaScript or TypeScript files (using a `.svelte.js` or `.svelte.ts` file ending)

+- when creating shared state, you can create a `$state` object containing the values you need and then manipulate said state
 
 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.

-In Svelte 5, the component lifecycle consists of only two parts: Its creation and its destruction. Everything in-between - when certain state is updated - is not related to the component as a whole, only the parts that need to react to the state change are notified. This is because under the hood the smallest unit of change is actually not a component, it's the (render) effects that the component sets up upon component initialization. Consequently, there's no such thing as a "before update"/"after update" hook.
