You are almost there, just use Object.values():

const person = { name:"Jack", family:"Miller", age: 27, cars:{car1:"Bens", car2:"Lexus"}}


for (let x in person){
  if(typeof person[x] === "object"){
    document.write(Object.values(person[x]).join(', ') + "<br>");        
  }else{
    document.write("_" + "<br>")
  }
}
