• length: The second parameter specifies the length of the final string.
  • If the length is smaller than the original length of the string, then the function removes the extra characters.

| paddedString    |
+-----------------+
| ConcatlyABCABCA |
+-----------------+

In the above example, the function pads “ABC” from right of the original string to make a total of 15 characters.
