Two-way data binding
We already mentioned it a number of times as one of the most convenient and widely-known features of Angular, as well as in many other reactive frameworks out there. Nonetheless, before going further, let’s ensure that we know what we’re talking about.

The good news is, since we’re using Angular, we’re already set; our application is already equipped with fully-functional two-way data binding between two Angular components that share a data bind via...
