In the course formControl is referred as controller. Is that correct ? Even if that is correct, there should be an indication that you are calling formControl as controller.
formControl is the class. We use the import statement of the
@angular/forms package to include the
FormControl class and these controls are added as key-value pairs in the object passed into the constructor function of the
FormGroup class. For every input in our form, we should add a new instance to the object.
