How to add to an array

Question

I have an empty array and can an add to it like so:

test.theme = [
];
test.theme.default = ['blue','pink','orange'];

How can I hard code default in to the theme array instead of first declaring the array and then adding to it?

I've been trying

test.theme = [
 default: ['blue','pink','orange']
]

Can't seem to get the right syntax.

• elclanrs: First example you're attaching a property to the array object, not as an index of the array, so your test.theme.length==0. In second example is not valid syntax. Do you want an object?

Answer 1

The array literal syntax makes no provisions for attaching properties (other than the implicitly-numbered properties, of course). You have to add the "default" property in a different statement, and you'll have to do it like this:

test.theme["default"] = ['blue', 'pink', 'orange'];

if you don't want some IE versions to get upset. (The word "default" is a JavaScript keyword.)

Answer 2

The first object is not an array, it's an object. Do it like this:

test.theme = {
 default: ['blue','pink','orange']
}

• Pointy: @MikeRifgin Good - note that you won't be able to use .push() or .slice() or .length on your "test.theme" object, but that may be what you want.
