Question

Say I have the following:

var a = '1',
    b = 'foo';

How do I create an object using the above variables such that my object looks like this:

'1' => 'foo'

I’m trying to make this like an associative array. Furthermore, I want 1 to contain an array of objects. I have the variable that have the array of object; I just need to put it in 1.

Answer 1

Use an object literal:

var myObject = { "1" : "foo" };

or, if you want to create it from variables, create a new object then assign things.

var myObject = {};
myObject[a] = b;

Furthermore, I want 1 to contain an array of objects

JavaScript doesn’t care what type the data is. b can be an array as easily as a string. (And you can use an array literal where you have a string literal in the short version)

var myObject = { "1" : [ 7, "foo", new Date() ] };
