how can a component destroy itself ?

[Cergoo]

Hi. I find on stackowerflow code

import {get_current_component} from 'svelte/internal'
const THISComponent = get_current_component()

function destroySelf(){
   THISComponent.$destroy();
}

is it correct ?

Not really. You should not use anything from svelte/internal, as the name suggests, those are internals which are not meant to be used by anything but Svelte itself.

There is no official mechanism for this. Usually the code that creates a component should destroy it.
E.g. if the component is done doing whatever it is supposed to be doing, fire an event and the parent code listens to that and destroys the component.

why? this is very strange.

import Login from './Login.svelte'
function create_component() {
	new Login({
			target: document.body,
	});
}

Most components are created via markup so Svelte handles their creation/destruction.
It generally would not make much sense if components can just disappear on their own, it would create a mismatch between markup and what is actually there.
