It normally takes two parameters: `start` and `length`. It can also take one parameter: `start`, i.e. `length` is omitted, in which case the substring starting from start until the end of the string will be returned.
|
|
|
|
To extract characters from the end of the string, use a negative start number.
|
|
|
|
In addition, borrowing from the extended behavior described at http://php.net substr, if `length` is given and is negative, that number of characters will be omitted from the end of string.

```
|
|
{{substr "BatMan" 0 -3}} → "Bat"
|
|
{{substr "BatMan" 3 3}} → "Man"
|
|
```
