JavaScript Arrays --

[Lugubrious]

I'm trying to make a two-dimensional array, if you get what I mean. Basically...

var opp=new Array();
opp[0]("love","hate");
opp[1]("happy","sad");


And I would like opp[0,1] be hate, etc. Is that possible? I know it is in some languages, but the code is giving me a hard time so it would be nice to know it that is possible. If it is impossible, how can I get around this?

The correct way to do something like that would be like this:

var opp=new Array();
opp[0] = ["love","hate"];
opp[1] = ["happy","sad"];

To access hate of the array would be opp[0][1] not opp[0,1].

There's several ways to write it, but this will do. And you don't use commas to separate the indices.

var opp = [
        ["love", "hate"],
        ["happy", "sad"]
];

opp[0][1] == "hate"

Thanks so much! Yall are the best.

While what Jordan posted is the new standard for arrays, hopefully this will help you understand the declaration of arrays.

var opp=new Array();
opp[0]("love","hate");
opp[1]("happy","sad");

should be

var opp = new Array();
opp[0] = new Array("love","hate");
opp[1] = new Array("happy","sad");

[] is synonymous with new Array()
var opp = [];
opp[0] = ["love", "hate"];
opp[1] = ["happy", "sad"];
is saying the same thing as the above example, and is the current JS standard (so use [] instead of new Array()).

What I'm getting to is: You can declare a value of an array (e.g. opp[0]) the same way you'd declare the array itself, or any other variable.
some_variable = [];
some_array[0] = [];

some_variable = "string";
some_array[1] = "string";



And I'm not sure if other languages support this (I know the outdated C++ I was learning ages ago didn't), but you can also do:
var opp = [
["an", "array", "for", "the", "first", "value"],
"a string for the second",
124959,
["back", "to", "an", "array"]
];

Each value can be anything, including an array, of any length.
