ReactiveForms in Angular are not actually all that reactive - unless we take a particularly loose definition of the word "reactive" to just mean that some kind of reactive mechanism like observables are used.

Most typical usage of ReactiveForms in Angular involves using a lot of imperative code and manual subscribes. This video explores using signalSlice as a way to make using ReactiveForms more reactive and declarative.
