how to solve these nin javascript : Locate the displayBirthdate function you initially defined, which took no parameter. Modify it to use object de-structuring to get just the 'dob' property of the parameter object it will receive

here's the code 

const displayBirthdate = () => {
       
      };

const displayExtraUserInfo = (extra) => {
         document.getElementById("btn-birthdate").addEventListener("click", ()=> {
                displayBirthdate(extra)
            })

"dob": {
        "date": "1986-02-19T23:25:07Z",
        "age": 33
      }

const getUser = () => ({
    date: 156-888,
    age: 20,
    
});
