Help with functions

Question

function person(name, age) {
this.name= name;
this.age = age;
this.yearOfBirth = bornYear;
}
function bornYear() {
return 2016 - this.age;
}

var p = new person("A", 22);

document.write(p.yearOfBirth());

why I can't write :
document.write(p.age());
to print the age from the function?

Answer 1

age property is not a function. it's an attribute. So Parenthesis not need there. You can call p.age but yearOfBirth is assigned a function so you need parenthesis () to call it..

Answer 2

Got it now, thanks for the explanation
