`trim`*requires* the second argument, which tells the function specifically what to remove from the first argument. There is no default value for the second argument, so **the following usage will not work**:
```
{{ trim .Inner}}
```
Instead, the following example tells `trim` to remove extra new lines from the content contained in the [shortcode `.Inner` variable][shortcodevars]:
```
{{ trim .Inner "\n" }}
```
{{% note %}}
Go templates also provide a simple [method for trimming whitespace](/templates/introduction/#whitespace) from either side of a Go tag by including a hyphen (`-`).
