    1. If it's behaviour that you can imagine needing to reuse among multiple components, or if it's something that you can imagine applying to an element inside an {#if ...} block (for example), then it probably belongs in an action. It it's something that 'belongs' to the component itself, rather than a specific element, then it's probably more of a lifecycle thing.
    2. The use:action method seems cleaner, but aside from that, are there any underlying differences between these two methods that would make one preferred over the other in certain situations?
    1. Popper for Svelte with actions, no wrapper components or component bindings required! Other Popper libraries for Svelte (including the official @popperjs/svelte library) use a wrapper component that takes the required DOM elements as props. Not only does this require multiple bind:this, you also have to pollute your script tag with multiple DOM references. We can do better with Svelte actions!

    1. For use$ since svelte is never going to support actions for components, i designed something that reminds React hooks that will in some ways replace this feature.

      Isn't that what use$ is trying to do already? How is that "something that reminds React hooks" any different? Will be interested to see...

    1. The point of the feature is to not rely on the third-party author of the child component to add a prop for every action under the sun. Rather, they could just mark a recipient for actions on the component (assuming there is a viable target element), and then consumers of the library could extend the component using whatever actions they desire.
    2. They don't need to add a prop for every action. The action itself can be passed in as a prop. <script> export let action; </script> <div use:action>whatever</div> The argument for the action can be another prop or can be part of the same prop.
    1. Your tooltip component will have to wrap your image with a span tag or something, it can’t just add events to its children. And if you are adding multiple actions to it you will have to wrap it multiple times.
