JSON Stringify a sublist

Question

JSON Stringify a sublist

This may be a noob question, but if I wanted to make a JSON list of items (in a nodejs app) I can do the following:

var myVar = {
  'title' : 'My Title',
  'author' : 'A Great Author'
};

console.log(JSON.stringify(myVar));

OUTPUT: { 'title' : 'My Title', 'author' : 'A Great Author' }

and everything works great, but how do I make a sublist like the following?

OUTPUT: { book {'title' : 'My Title', 'author' : 'A Great Author'} }

javascript
json
node.js

Answer 1

{} is the object literal syntax, propertyName: propertyValue defines a property. Go ahead and nest them.

var myVar = {
    book: {
        'title' : 'My Title',
        'author' : 'A Great Author'
    }
};

Answer 2

To do it with JavaScript:

var mVar = {
  'title'  : 'My Title',
  'author' : 'A Great Author'
};

var myVar = {};

myVar.book = mVar;

console.log(JSON.stringify(myVar));

To do it using the object literal notation:

var myVar = {
  'book': {
      'title'  : 'My Title',
      'author' : 'A Great Author'
  }
};

console.log(JSON.stringify(myVar));

Answer 3

As so:

var myVar = {
  'book': {
      'title' : 'My Title',
      'author' : 'A Great Author'
  }
};

Answer 4

You'd do something like this:

myVar = {
    book: {
        'title' : 'My Title',
        'author' : 'A Great Author'
    }
}

console.log(JSON.stringify(myVar)); // OUTPUT: { book {'title' : 'My Title', 'author' : 'A Great Author'} }

If you wanted multiple items in the sublist, you'd change it to this:

myVar = {
    book1: {
        'title' : 'My Title',
        'author' : 'A Great Author'
    },
    book2: {
        'title' : 'My Title',
        'author' : 'A Great Author'
    }
}
