Since NgModel created the FormControl instance to manage the template form control in the first place, it stored a reference to that FormControl in its control property which we can now access in the template like so email.control.touched.This is such a common use case that the ngModel directive provides us a shortcut to the control property, so we can just type email.touched instead. Zone pollution. When you run the ng build (build only) or ng serve (build and serve locally) CLI commands, the type of compilation (JIT or AOT) depends on the value of the aot property in your build configuration specified in angular.json.By default, aot is set to true for new CLI applications.
