Laravel – Array rendering is reversed when editing post

I have the following Livewire code, it lists all the chirps (posts) I have; the problem is that when I click to edit one of the chirps, the whole $chirps array seems to render upside down. I added the id of each chirp for clarity:

The actual editing process works just fine.

<?php

use LivewireVoltComponent;
use AppModelsChirp;
use IlluminateDatabaseEloquentCollection;
use LivewireAttributesOn;

new class extends Component {
    public Collection $chirps;

    public ?Chirp $editing = null;

    public function mount(): void
    {
        $this->getChirps();
    }

    #[On('chirp-created')]
    #[On('chirp-updated')]
    public function getChirps(): void
    {
        $this->editing = null;
        $this->chirps = Chirp::with('user')
            ->latest()
            ->get();
    }

    #[On('chirp-edit-cancelled')]
    public function resetEdittingChirp()
    {
        $this->editing = null;
    }

    public function edit(Chirp $chirp): void
    {
        $this->editing = $chirp;
    }
}; ?>

    Instead of…

    @foreach ($chirps as $chirp)

    Use:

    @foreach ($chirps->sortByDesc('created_at') as $chirp)

    Also, Livewire provides the wire:key directive, which can be used to explicitly set a unique key for each element in a loop.

    <div wire:key="{{ $chirp->id }}" class="p-6 flex space-x-2">

    Try this:

     @foreach ($chirps->sortDesc('created_at') as $chirp)

    it will sort the chirps in descending order.

    By sorting the chirps before rendering, you should maintain the desired order when you edit a chirp.
