As an example of how this features works pretend you have a layout.blade.php file that includes this:

<ul id="sidebar">
    @stack('sidebar')
</ul>

Now when you want to insert data into this section from a sub-view you can add:

@push('sidebar')
    <li>Sidebar list item</li>
@endpush

Once this is rendered in the browser the results are an unordered list:

<ul id="sidebar"> 
    <li>Sidebar list item</li> 
</ul>

Now since v5.4.10 a new prepend directive has been which allows you to push an item to the front of the stack before it’s rendered.

For example:

@push('sidebar')
    <li>Sidebar list item</li>
@endpush
@prepend('sidebar')
    <li>First Sidebar Item</li>
@endprepend

Now, the results will be:

<ul id="sidebar">
    <li>First Sidebar Item</li>
    <li>Sidebar list item</li>
</ul>

This will be great in those situations where you need to push items to the front of the stack.
