String.prototype.padStart(), String.prototype.padEnd()

- OTHER

The padStart() and padEnd() methods pad the current string with a given string (eventually repeated) so that the resulting string reaches a given length. The pad is applied from the start (left) of the current string for padStart(), and applied from the end (right) of the current string for padEnd().
