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

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

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.
