Create a string of variable length, filled with a repeated character

Question

So, my question has been asked by someone else in it\'s Java form here: Java - Create a new String instance with specified length and filled with specific character. Best so

Answer 1

I would create a constant string and then call substring on it.

Something like

var hashStore = '########################################';

var Fiveup = hashStore.substring(0,5);

var Tenup = hashStore.substring(0,10);

A bit faster too.
