Is Angular4 really 2-Way data-Binding?

What I have learned of Angular2/4/5/6 is that due to [(ngModel)] the 2-way data binding is possible in it -- Just like it happend in Angular1 via $scope.

Now, I came across this website which clearly states that 2-Way data binding is not possible in Angular4. I am highly confused. Can someone really clarify that -- whether 2-Way data binding is possible or Not in Angular 2/4/5/6?

    whether 2-Way data binding is possible or Not in Angular 2/4/5/6?

    Nope, it is not [(ngModel)] is not two-way data binding. It’s just a syntactic sugar for a simultaneous event binding and property binding.
