it's scala

cool

lol that's a great 7kyu kata. like being basic yet revealing some of mine elementary math illiteracy

nowadays it feels more like a 7kyu, if not an 8

it would be cool if there was a restricted version of this accepting only bitwise operations solutions

The String Numeric test is insufficient. Added a console.log for an invalid solution that failed a moment ago, but the next run it passed suddenly

i've never seen decltype before. looks cool

lgtm

never knew undefined would evaluate like that with bitwise ops. meanwhile undefiend + 1 equals NaN

cool

I didn't get it at first but that multibyte character handling is really neat. thanks

well yeah, the "position" arguments are actually [y, x], not [x, y]

This is the most upvoted "best practices" solution, but is it actually valid? (asking pattern theoriests)

A decorator will receive an instance of the base class and use it to create a new instance with the new things you want "added on it".

The solution doesn't seem to conform that

OMG what a kata. Enjoyed it a lot
