//require the library
const ench = require("ench");
//determine which characters we will iterate over
const v = "abcdefghijklmnopqrstuwxyzABCDEFGHIJKLMNOPQRSTUWXYZ0123456789-_=+)(*&^%$#@!;:?";
//indicate the starting position
let str = "aaa";
//create new ench object
const gen = new ench();
//do the test, print 10 sequences
let i=0;
while(i<10){
str = gen.next(0,str,v);
console.log(str);
i++;
}
//console.log
//aab
//aac
