User control not validating an accommodating learning style
32) A session-based system authenticates a user to a Web site to provide access to restricted resources.
To increase security in this scenario, an authentication token should meet which of the following requirements?
This component will display actual validation failure messages inline, next to the input elements themselves. But we are going to be implementing this interface on all of our input elements, so rather than copy and paste the same code into all of our form elements, we will create an abstract base class that manages the is used to update the value of our control, but it takes an argument of type any.
In fact almost all of these methods just accept arguments of type any and therefore it’s a poor interface declaration.
This allows us to also explicitly list each form control’s validators.
The first parameter in the control we leave empty as this lets you initialize your form control with a value. Angular has some built in Validators such as syntax.
