-
-It normally takes two argument: `start` and `length`. It can also take one argument: `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.
-
-If `length` is given and is negative, that number of characters will be omitted from the end of string.
