Pads this string on the left if it is shorter than width
.
Return a new string that prepends padding
onto this string one time for each position the length is less than width
.
If width
is already smaller than or equal to this.length
, no padding is added. A negative width
is treated as zero.
If padding
has length different from 1, the result will not have length width
. This may be useful for cases where the padding is a longer string representing a single character, like " "
or "\u{10002}
". In that case, the user should make sure that this.length
is the correct measure of the strings length.
