Wouldn't the wrapping also need to remove the opening `[` as well?  I'd do something like:

```coffeescript
text = text.replace /\[(.*?)\]\((.*?)\)/g, '$1'
```

Also, the `.*?` syntax there is a cool way to prevent issues like where there are multiple links. For example, `"This is a [test](http://google.com) foo [bar](http://baz.com)"` would turn into just `"This is a "` without them.
