• Looks like you're just testing how Laravel and JS work. Put this code into the Blade view you're executing. If you've just installed Laravel, put this to resources/view/wele.blade.php – Alexey Mezenin Commented Jan 23, 2018 at 13:37

Try:

echo "<script>";
echo "alert('hello');";
echo "</script>";

Or try this:

return redirect()->back()->with('alert','hello');

@push('stylesheets')
    <link rel="stylesheet" href="custom/css/required/by/child">
@endpush

@push('scripts')
    <script src="custom/js/required/by/child"></script>
@endpush
