What’s wrong with this code not printing?

Question

const Person1= new Person("John", "Kennedy", "3-6-1895");
const Person2= new Person("Mary", "Kennedy", "3-6-1995");
class Person{
constructor Person =(firstName, lastName, dob){
this.firstName =firstName;
this.lastNsme =lastName;
this.bod= new Date(dob);
}
getBirthYear{
return this.bod.getBirthYear;
}
getFullName{
return ${this.firstName} ${this.lastName}
}
}

document.write(Person2.getFullName());
document.write(Person1);

Answer 1

//The full code simplified and should work mow🙃😉🙃
//And you made a typo in the code in this.lastName, yiy write this.lastNsme by accident😉🙃

class Person{
constructor (firstName, lastName, dob){
this.firstName =firstName;
this.lastName =lastName;
this.bod= new Date(dob);
}
getBirthYear(){
return this.bod.getBirthYear;
}
getFullName(){
return this.firstName+" "+this.lastName
}
}

const Person1= new Person("John", "Kennedy", "3-6-1895");
const Person2= new Person("Mary", "Kennedy", "3-6-1995");
document.write(Person2.getFullName());
document.write(Person1);

have seen the mistake. thanks buddy

Answer 3

1. You should put `backticks` around the ${this.firstName} ${this.lastName} bit
2. Unlike other programming languages, JS class constructors just need the constructor keyword:
class Person {
constructor(firstName, lastName, dob) {
// Do something
}
}
Hope this helps.
