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.
If length
is given and is negative, that number of characters will be omitted from the end of string.
