[Angular 2] ng-control & ng-control-group

Control:

Controls encapsulate the field's value, a states such as if it is valid, dirty or has errors.

var nameControl = new Control("Nate");
var name = nameControl.value; // -> Nate
 
nameControl.errors // -> StringMap<string, any> of errors
nameControl.dirty // -> false
nameControl.valid // -> true

ControlGroup:

A way to manage multiple Controls.

var personInfo = new ControlGroup({
    firstName:  new Control("Nate"),
    lastName: new Control("Murray"),
    zip: new Control('90210')
});
 
personInfo.value; // ->{
   //firstName: "Nate",
   //lastName: "Murray",
   //zip: "90210"
}
 
personInfo.errors // -> StringMap<string, any> of errors
personInfo.dirty // -> false
personInfo.valid // -> true
