Answer 1

Couple of simple changes.

function person(name,age,height){
this.name=name;
this.age=age;
this.yearofbirth=yob(this.age);
}
function yob(age){
return 2020-age;
}
var x=new person("me",23);

console.log(x);

Answer 2

this.x can only be used in class

Try this

class person {
constructor (name,age){
this.name=name;
this.age=age;
}
yob() {
return 2020-this.age;
}
}

var x=new person("me",23);
var yr=x.yob();

console.log(yr);

Already described here:

You just need to write like this:

console.log(x.yearofbirth())

--------+------

function person(name, age) {
this.name=name;
this.age=age;
this.yearofbirth=yob;
}
function yob(){
return 2020-this.age;
}
var x=new person("me",23);
console.log(x.yearofbirth())

Answer 4

I don't quite understand what you want but if you want an output you can use console log
console.log(x.yearofbirth());
