How can you change this array:

```
[["1","one"], ["2","two"], ["3","three"]]

```

to this?

```
["1","one"], ["2","two"], ["3","three"]

```

Clarification
-------------

My apologies for giving an invalid second version. This is what I'm really going for:

I want to add `["0","zero"]` to the beginning of `[["1","one"], ["2","two"], ["3","three"]]`, to get:

```
[["0","zero"], ["1","one"], ["2","two"], ["3","three"]]

```

I have tried:

```
["0","zero"] << [["1","one"], ["2","two"], ["3","three"]]

```

The above approach produces this, which contains a nesting I don't want:

```
[["0","zero"], [["1","one"], ["2","two"], ["3","three"]]]

```
