setLength
Sets the length of this string builder to the specified newLength .
If the newLength is less than the current length, it is changed to the specified newLength . Otherwise, null characters '\u0000' are appended to this string builder until its length is less than the newLength .
Note that in Kotlin/JS set operator function has non-constant execution time complexity. Therefore, increasing length of this string builder and then updating each character by index may slow down your program.
