Basics

const [name, setName] = useState('Edward');
const [age, setAge] = useState('0');


function handleClick() {
  setName('Taylor');
  setAge(a => a + 1);
}

as react batches states updates so it when it is called multiple times it may not update correctly so this updater function/functional form helps
