Write a JS function to divide all numeric properties in 2.

let salaries = {
    John : 100,
    Ann : 160,
    Pete : 130,
}

let cafe = {
    age : "20",
    name: "John",
    salary : 2400,
}

function createHalfValuesCopy (obj) {
    let copy = {};
    for (let key in obj) {
      copy[key] = divideInTwoOrReturnOrigin(obj[key]);
    }
    return copy;
  }

function divideInTwoOrReturnOrigin (number) {
    if (typeof number === 'number') {
        return number / 2;
    }
    return number;
}
