The main purpose of this class is to provide the view model with the App
instance, thus giving it access to the various helper methods available in
that class. Additionally, it provides an instance of Escaper, allowing you
to do context-specific escaping within helpers you define in the view model.
public function testCanPassEscaperInstanceToConstructor()
{
$escaper = new Escaper();
$model = new MustacheViewModel($this->app, $escaper);
$this->assertSame($escaper, $model->__escaper());
}
