Now we have integrated with React to make our UI a deterministic representation of our state. However, as demonstrated when you tried typing in the input box, there’s no way for us to update the state. Let's change that now.
Just to recap, the way you change a state in Redux is by dispatching an action, and defining reducers that react to those actions and update the state.
Let’s start with a scenario where we are updating the state; for instance, when we type in the input box in one of the forms. At the moment, we are using the handleInputChange method to update the local state:
handleInputChange = (name, event) => { const value = event.target.value; const valid = validator[name](value); this.setState({ [name]: { value, ...
