normally i would just use obj.hasOwnProperty() directly here, but I guess we don't allow that with this rule: https://eslint.org/docs/rules/no-prototype-builtins

const updatedBalanceFromStore =
balance === EMPTY && selectedAddress === address && selectedAccount && selectedAccountHasBalance
? selectedAccount[BALANCE_KEY]
: balance;
return {
updatedBalanceFromStore
};
};

export default connect(mapStateToProps)(AccountElement);
