Fun kata, I was quite confused about what the task entailed upon reading the description and had to rely on the examples. Re-reading it a few times, I'd recommend changing this in the description:
"filter out all letters and return unique integers as a string" -->
"filter out all letters and duplicate integers to return only unique integers as a string"
And in the example at the bottom of the description, consider adding a simple comment to clarify why the lottery would return "One more run!":
var str = "ynMAisVpHEqpqHBqTrwH"; -->
var str = "ynMAisVpHEqpqHBqTrwH"; //contains no integers
Java Translation kumited. Please check out, thank you! :)
Node.js needs an update.. It's still using version 8..
This is a bad tip, and teaches people a bad practice. Please, remove it from the description.
