Adding data to a JavaScript object literal

Question

This is my object literal: ``` var obj = {key1: value1}; ``` How can I add ``` {key1: value1,value2,value3} ``` to `obj`?

Accepted Answer

The value of your object would have to be an array or object that stores the separate values, like so:

```
{key1: [value1,value2,value3]}
```

Or

```
{key1: new compositeValue(value1, value2, value3)}
```
