How to fill a Javascript object literal with many static key/value pairs efficiently?

Question

The typical way of creating a Javascript object is the following:

var map = new Object();
map[myKey1] = myObj1;
map[myKey2] = myObj2;

JavaScript's object literal syntax, which is typically used to instantiate objects (seriously, no one uses new Object or new Array), is as follows:

var obj = {
    'key': 'value',
    'another key': 'another value',
     anUnquotedKey: 'more value!'
};

For arrays it's:

var arr = [
    'value',
    'another value',
    'even more values'
];

If you need objects within objects, that's fine too:

var obj = {
    'subObject': {
        'key': 'value'
    },
    'another object': {
         'some key': 'some value',
         'another key': 'another value',
         'an array': [ 'this', 'is', 'ok', 'as', 'well' ]
    }
}

This convenient method of being able to instantiate static data is what led to the JSON data format.

JSON is a little more picky, keys must be enclosed in double-quotes, as well as string values:

{"foo":"bar", "keyWithIntegerValue":123}
