Laravel JavasScriptへデータを渡す書き方

HTML同様、scriptタグ内でも{{$variable}}と書くとデータが渡る

$ php artisan make:controller AdminController

web.php

Route::get('/', 'HomeController@index');
Route::get('/admin', 'AdminController@index');

AdminController.php

class AdminController extends Controller
{
    //
    public function index(){
    	return view('admin/index');
    }
}

AdminController.php

public function index(){
    	$postsCount = Post::count();
    	$categoriesCount = Category::count();
    	$commentsCount = Comment::count();

    	return view('admin/index',compact('postsCount','categoriesCount','commentsCount'));
    }

index.blade.php

<script src="https://cdn.jsdelivr.net/npm/chart.js@2.9.3/dist/Chart.min.js"></script>
<script>
var ctx = document.getElementById('myChart').getContext('2d');
var myChart = new Chart(ctx, {
    type: 'bar',
    data: {
        labels: ['Posts', 'Categories', 'Comments'],
        datasets: [{
            label: 'Data of CMS',
            data: [{{$postsCount}},{{$categoriesCount}},{{$commentsCount}}],
            backgroundColor: [
                'rgba(255, 99, 132, 0.2)',
                'rgba(54, 162, 235, 0.2)',
                'rgba(255, 206, 86, 0.2)',
                'rgba(75, 192, 192, 0.2)',
                'rgba(153, 102, 255, 0.2)',
                'rgba(255, 159, 64, 0.2)'
            ],
            borderColor: [
                'rgba(255, 99, 132, 1)',
                'rgba(54, 162, 235, 1)',
                'rgba(255, 206, 86, 1)',
                'rgba(75, 192, 192, 1)',
                'rgba(153, 102, 255, 1)',
                'rgba(255, 159, 64, 1)'
            ],
            borderWidth: 1
        }]
    },
    options: {
        scales: {
            yAxes: [{
                ticks: {
                    beginAtZero: true
                }
            }]
        }
    }
});

controllerのdataの取得は、count()以外にも、JSで表現したい内容に合わせてControllerで取得・整形する
JS側ではなくController側で整えるのが一般的か
