Can you be a little more specific as to what the problem is. I do not see anything wrong with your creation of an array of objects.

What's your actual question?

Yes, you can mix objects and arrays; In fact, arrays are just special, numerically keyed objects - If you typeOf on it, an array will be an Object type. The key difference between arrays and objects is that arrays are declared as a set of comma separated values inside square brackets, ["value1", "value2"], while objects are declared with curly braces, keys, and values, {key1 : "value1" , key2 : "value2"}.

You can also have multi-dimensional objects and arrays; In other words, an array of arrays, an object of arrays, an array of objects, etc. etc. You declare them in the same way, just nested inside eachother. For example, an array of objects would look like: 

var objects = [
  {key: 'keyValue1', answer: 'answerValue1'},
  {key: 'keyValue2', answer: 'answerValue2'},
  {key: 'keyValue3', answer: 'answerValue3'}
];

Hope that helps

Thank you so much. I just had the question answered. I did not realize that the quotations were needed for the answers too. Thank you.

You're welcome. Yes, strings always go in quotes, while numbers never do.

Just some food for thought on forum etiquette... This would have been better as a comment, rather than an additional Answer. Also, is it possible to upvote and select my answer as Best Answer?
