Doesn't an object need to have a name?

Take this for example:

var questions = [ { question: 'How many states are in the United States?', answer: 50}, { question: 'How many continents are there?', answer: 7}, { question: 'How many legs does an insect have?', answer: 6 } ];

"questions" is the name of the array, but since the array consists of three objects, don't the objects themselves need individual names?

You might be thinking of a "class" name, but these object literals don't have a class association.

These objects can all be identified by the name "questions" combined with an index. Fpr example, the "name" of the object related to insects is "questions[2]". It's essentially the same situation you would have with this code:

var numbers = [ 2, 4, 6 ];

If I were to ask "what expression will access the number 4?", the answer would be "numbers[1]".
