How can i create a partially nested array?

Question

I have a question with multiple answers. I want an array that has two spots, the first can only hold one value (one question), the second can hold an array (multiple answers).

Question: 'favorite colors' Answers: 'blue' 'black' 'red'

var answer = [];
var question [[],answer];

I'm unable to get this to work properly. :(

 var list = [ 'favorite colors', ['red','black'] ];

But I would do something like this instead:

 var question = { question: 'Favorite color',
   answers: ['red','black']
 }

 var list = [ question, ... ];

Is it what you wanted?

var question = 'What is your favourite color?';
var answers = ['blue', 'yellow', 'black', 'pink', 'omg, ponies!'];

var your_array = [question, answers];

or without immediate variables:

var your_array = [
    'What is your favourite color?', // question here
    ['blue', 'yellow', 'black', 'pink', 'omg, ponies!'] // answers array here
];

To get the question you do:

var your_question = your_array[0];

To get the list (array) of answers you do:

var your_answers = your_array[1];

how would i pick the second choice(yellow) in the array? just your_array[1][1]?

@user1082764: To get the second answer you will need to do it like that: your_array[1][1]. Its because the arrays are indexed beginning with 0 (zero), and this array is multidimensional. The first dimension choses answers (your_array[1]) that lie on the second position (thus [1]), and the second dimension choses second position within what you get so far (so the second position within the answers).

I am struggling a to understand multidimentional arrays, you've been great help!

@user1082764: Good to know. If it helps, you can treat every part with brackets separately (because it is how it works). your_array[1][1] really means: 1) your_array means "get your_array variable", 2) [1] means "get second element of what you got so far, from point 1)", 3) the second [1] means "get the second element of what you got so far, from point 2)".
