```go-html-template
{{ trim "++Batman--" "+-" }} → "Batman"
```

`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**:

```go-html-template
{{ trim .Inner }}
```

Instead, the following example tells `trim` to remove extra new lines from the content contained in the [shortcode `.Inner` variable][shortcodevars]:

```go-html-template
{{ 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 (`-`).
{{% /note %}}
