Question

Say I want the object to be something like this:

var Book = {
        title: "the catcher in the rye",
        price: "80.98",
        characters: [{name: "holden caulfield", age: 16, height:"6.2"},
                     {name: "phoebe caulfield",age:13, height: "5"}] 
     };

EDITED

question:
characters array is built by adding a character one by one. How can do this while making sure that name, age and height properties are defined as above.

Something to the effect of?

Book.characters.add({name: "phoebe caulfield",age:13, height: "5"});

I would like to be able to define this programmatically, ie add properties to the object rather than define it like this.

Is this possible?

Answer 1

You can do it in dynamic code (rather than a static declaration) like this:

var Book = {};

Book.title = "the catcher in the rye";
Book.price = "80.98";
Book.characters = [];
Book.characters.push({name: "holden caulfield", age: 16, height: "6.2"});
Book.characters.push({name: "phoebe caulfield", age: 13, height: "5"});
