I´m trying to pass a value inside of my function but the result is undefined

function ExpanseTable() {

const [month, setMonth] = useState('Dec')
console.log(month + "     outside function") // Dec



const updateMyData = (rowIndex, columnId, value, id, testValue ) => {
  console.log(month + "     inside function") //undefined
  };
}

updateMyData is called in

 <Table
    updateMyData={updateMyData}
  />
