How to update nested state properties in React

Question

I\'m trying to organize my state by using nested property like this:

this.state = {
   someProperty: {
      flag:true
   }
}

But updating

Answer 1

This is my initialState

    const initialStateInput = {
        cabeceraFamilia: {
            familia: '',
            direccion: '',
            telefonos: '',
            email: ''
        },
        motivoConsulta: '',
        fechaHora: '',
        corresponsables: [],
    }

The hook or you can replace it with the state (class component)

const [infoAgendamiento, setInfoAgendamiento] = useState(initialStateInput);

The method for handleChange

const actualizarState = e => {
    const nameObjects = e.target.name.split('.');
    const newState = setStateNested(infoAgendamiento, nameObjects, e.target.value);
    setInfoAgendamiento({...newState});
};

Method for set state with nested states

const setStateNested = (state, nameObjects, value) => {
    let i = 0;
    let operativeState = state;
    if(nameObjects.length > 1){
        for (i = 0; i < nameObjects.length - 1; i++) {
            operativeState = operativeState[nameObjects[i]];
        }
    }
    operativeState[nameObjects[i]] = value;
    return state;
}

Finally this is the input that I use
