I want to set both of these values in the state to be used later as variables.

  const [dollarGoal, setDollarGoal] = React.useState(0); 
  const [dollarValue, setDollarValue] = React.useState(0);
  //fetching donation value
  fetch('api', {
      method: 'GET',
    })
    .then(response => response.json())
    .then(r => setDollarValue(r.dollarValue))
    .then(r => setDollarGoal(r.dollarGoal));

But it gives the error:

Property 'dollarGoal' does not exist on type 'void'.

How do I fix this?
