Creating JSON object from Typescript class

Question

I have a class Person and after setting its properties, figuring out best way to convert that class to json object.

class Person {
    firstName: string;
    lastName: string;
}

let person = new Person();
person.firstName = "FirstName";
person.lastName = "LastName";

If i do person.getJson() it should give json object as given below

{
  "firstName": "FirstName",
  "lastName": "LastName"
}

and incase lastName is not set then json object should only have firstName

{
  "firstName": "FirstName"
}

You don't need a getJson() method on class Person. You can just call

JSON.stringify(person);

If you really want to put in your class...

class Person {
    firstName: string;
    lastName: string;
    getJson() {
        return JSON.stringify(this);
    }
}
