How to iterate through all properties and its values in Typescript class

Question

How do I iterate through list of class properties and get the values of each (only the properties and not the functions)

class Person{
 name:string;
 age:number;
 address:Address;
 getObjectProperties(){
   let json = {};
    // I need to get the name, age and address in this JSON and return it
    // how to do this dynamically, rather than getting one by one 
    // like json["name"] = this.name;
   return json;
 }
}

Please help.

You can't do that, if you look at the compiled code of:

class Person {
    name: string;
    age: number;
    address: Address;
}

You'll see that those properties aren't part of it:

var Person = (function () {
    function Person() {
    }
    return Person;
}());

Only if you assign a value then the property is added:

class Person {
    name: string = "name";
}

Compiles to:

var Person = (function () {
    function Person() {
        this.name = "name";
    }
    return Person;
}());

You can use a property decorator for that.
