```
|

{{ 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**:
|
||
|
|
|
||
|
|
```
|
||
|
|
{{ 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 (`-`).
|
||
|
|
{{% /note %}}
