// Write code under this line
const calculateTotalBalance = array => array.reduce((totalBalance, user) => totalBalance + user.balance , 0);

//console.log(calculateTotalBalance(users)); 
// 20916

Answer 1

Your error already gave you an answer, you should use destructuring assignment for balance

const calculateTotalBalance = array => array.reduce((totalBalance, { balance }) => totalBalance + balance , 0);
