Question 6

Which template engine does Laravel use?

Accepted Answer

Laravel uses **Blade Templating Engine.**

Blade is the simple, yet powerful templating engine provided with Laravel. Unlike other popular PHP templating engines, Blade does not restrict you from using plain PHP code in your views. In fact, all Blade views are compiled into plain PHP code and cached until they are modified, meaning Blade adds essentially zero overhead to your application. Blade view files use the .blade.php file extension and are typically stored in the `resources/views` directory.

Question 10

What is the Facade Pattern used for?

Accepted Answer

**Facades** provide a *static* interface to classes that are available in the application's service container. Laravel facades serve as *static proxies* to underlying classes in the service container, providing the benefit of a terse, expressive syntax while maintaining more testability and flexibility than traditional static methods.

All of Laravel's facades are defined in the `Illuminate\Support\Facades` namespace. 
Consider:
```js
use Illuminate\Support\Facades\Cache;

Route::get('/cache', function () {
    return Cache::get('key');
});
```
