mapStateToProps - strict filtering done by destructuring

example.js

// es6

const aStateThatCanBeSliced = {
  fruits: {
    oranges: 999999,
    bananas: 10
  },
  hasFreshFruits: true,
}

const aStateThatCannotBeSliced = {
  goats: 999
}


// Proposal

const mapStateToProps = state => {
  const { fruits: { bananas } } = state;

  return { fruits: { bananas } };
}

console.log(mapStateToProps(aStateThatCanBeSliced))  // => { fruits: { bananas: 10 } }
console.log(mapStateToProps(aStateThatCannotBeSliced))  // TypeError
