| ```
 | |
| {{ 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 %}}
