    21  ```
    22  {{ trim "++Batman--" "+-" }} → "Batman"
    23  ```
    24  
    25  `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**:
    26  
    27  ```
    28  {{ trim .Inner}}
    29  ```
    30  
    31  Instead, the following example tells `trim` to remove extra new lines from the content contained in the [shortcode `.Inner` variable][shortcodevars]:
    32  
    33  ```
    34  {{ trim .Inner "\n" }}
    35  ```
    36  
    37  {{% note %}}
    38  Go templates also provide a simple [method for trimming whitespace](/templates/introduction/#whitespace) from either side of a Go tag by including a hyphen (`-`).
    39  {{% /note %}}
