Convert object to array of prorperties

I need to convert object:

{
        middleName: null,
        name: "Test Name",
        university: {
            country: {
                code: "PL"
            },
            isGraduated: true,
            speciality: "Computer Science"
        }
    }

to array:

[{
        key: "name",
        propertyValue: "Test Name",
    },
    {
        key: "middleName",
        propertyValue: null,
    },
    {   
        key: "university.isGraduated",
        propertyValue: true,
    },
    {   
        key: "university.speciality",
        propertyValue: "Computer Science", 
    },
    {   
        key: "university.country.code",
        propertyValue: "PL"
    }];

I wrote algorithm, but it’s pretty dummy, how can I improve it? Important, if object has nested object than I need to write nested object via dot (e.g university.contry: "value")

let arr = [];
    Object.keys(parsedObj).map((key) => {
        if (parsedObj[key] instanceof Object) {
            Object.keys(parsedObj[key]).map((keyNested) => {
                if (parsedObj[key][keyNested] instanceof Object) {
                    Object.keys(parsedObj[key][keyNested]).map((keyNestedNested) => {
                        arr.push({ 'key': key + '.' + keyNested + '.' + keyNestedNested, 'propertyValue': parsedObj[key][keyNested][keyNestedNested] })
                    })
                } else {
                    arr.push({ 'key': key + '.' + keyNested, 'propertyValue': parsedObj[key][keyNested] })
                }
            })
        } else {
            arr.push({ 'key': key, 'propertyValue': parsedObj[key] })
        }
    });

Thanks

A recursive function implementation.

I have considered that your object consist of only string and object as the values. If you have more kind of data types as your values, you may have to develop on top of this function.

const myObj = {
  middleName: null,
  name: "Test Name",
  university: {
    country: {
      code: "PL"
    },
    isGraduated: true,
    speciality: "Computer Science"
  }
}
const myArr = [];

function convertObjectToArray(obj, keyPrepender) {
  Object.entries(obj).forEach(([key, propertyValue]) => {
    if (typeof propertyValue === "object" && propertyValue) {
      const updatedKey = keyPrepender ? `${keyPrepender}.${key}` : key;
      convertObjectToArray(propertyValue, updatedKey)
    } else {
      myArr.push({
        key: keyPrepender ? `${keyPrepender}.${key}` : key,
        propertyValue
      })
    }
  })
}

convertObjectToArray(myObj);
console.log(myArr);
