How Can I create a Google spreadsheet with two sheets in javascript using Google sheets API?

Question

I'm trying to create a Google Spreadsheet with two sheets or 'tabs' Using javascript. I can Create a sheet and add a title to a tab, but I can only create one tab. I have tried to use the addSheet property as well and it simply over-writes existing sheet. This is the data I'm trying to send as an example:

var data = {
  properties: {
    title: 'Data Sheet'
  },

  sheets: [{
    properties: {
      title: 'data A',
    },
    properties: {
      title: 'data B',
    }

  }]
};

Answer 1

I was missing additional brackets around my data. Simple mistake:

var data = { properties: { title: 'Data Sheet' },

                    sheets : [
                        {
                            properties: {
                                title: 'data A',
                            }
                        },
                        {
                            properties: {
                                title: 'data B',
                            }
                        }
                    ]
                };
