createReducer

createReducer - Creator

This function allows us to create our own reducer based on an object.

Receives an initialState and a reducer description.
Example:

const reducerDescription = {
  'ACTION_NAME': (state, action) => ({ ...state, aTarget: ':)' })
}

const initialState = { aTarget: null };
export default createReducer(initialState, reducerDescription);

So, we may do:

dispatch({ type: 'ACTION_NAME' });

And then the state will be like:

state = {
  aTarget: ':)'
};
