Getters and setter in javascript

JavaScript
1

Hi all,
it was mentioned on JS course that we use getters to access a property and setter to mutate a property.

How can I create a person object as below, and use getter to have read-only property on the firstName and a setter to be able to mutate the lastName?

Apparently I am able to create this object and being able to have access to ready-only using get, but how can I implement a setter?

const person = {
  get firstName() {
    return 'John';
  },
  set firstName(value) { //this part gives me a range error;
    return this.firstName = value;
  },
  lastName: 'Smith',
}


person.firstName = 'David'
console.log(person.firstName)

you can try this code:

const person = {
get firstName() {
return ‘John’;
},
set lastName(value) {
return this.lastName = value

},
lastName: 'Smith',

}

person.lastName = ‘bob’

console.log(person.lastName);
