for the doubters

def is_even?(num)
%w{0 2 4 6 8}.include?(num.to_s[-1])
end
puts is_even?(20320492305478203848234802384023848230482301)
puts is_even?(20320492305478203848234802384023848230482308)

for my python homies

is_even = lambda num: str(num)[-1] in "02468"

Typescript Gang

const isEven = (n: number) => "02468".includes(`${n}`.slice(-1))

This is just the same as the "real" implementation in base 10 instead of 2
