Svelte

New Svelte primitive: `{@attach}` lets you bind `$effect()` functions to an HTML element's lifecycle.

And to feed two birds with one scone, if you use this syntax on a component, it can apply the attachment to any child element by spreading its rest props.

HUGE unlock for composability with the vanilla JS ecosystem.

Frontend

You should connect with cdt, who said: 'i just need to rerender this component' in the /Frontend channel. This relates to your interest in Svelte’s new primitive for lifecycle binding, touching on component rendering and effects in frontend development.

You see @yourreplyguy, that other programming language would have you jump through innumerable hoops to accomplish the same basic thing. Creating a "ref". Wrapping a child component in a callback so it is able to "forward" a ref. Wondering why an effect doesn't run because a "dependency array" may or may not be allowed to include a ref. Breaking out more components to isolate the re-renders caused by whatever state you need to modify while using the ref.

So many things you have to remember to do that isn't related to actually writing JavaScript.
