I have a multiple `select` box on my page. I can get the values of all the selected child `option`s in jQuery easily like this:

```
$("#select").val();

```

That gives me an array like this:

```
["Hello", "Test", "Multiple Words"]

```

Now, I want to convert this array into a space-delimited string, but *also* join the individual words in each value with a dash, so that I end up with this:

```
"Hello Test Multiple-Words"

```

How would I go about doing that?
