It only seems to work on node 8

It's because parseInt takes 2 parameters and I forgot that. I fixed it now.

This is my fault. I forgot that parseInt takes a second parameter which completely changes the behavior. It should be fixed now.

A'ight, this kata has me thrown for a loop. There are some tests that appear that yield one result on the master test, but seem as though they should fail the problem as described. It seems to come down to how Array.prototype.some behaves when handed parseInt?

For example, one generated test:

seq = [
'JDQIAXYXUNBLWRAJSFXT',
'D',

'UYJMHZ',
'XBIHTBFUBBNZLOXRGFFABJKJFPI',

pred = parseInt

And the output of using this sequence is:

seq.every(parseInt) == false
seq.some(parseInt) == true
seq.some(x=>parseInt(x)) == false

So a solution that runs seq.some(pred) will get a different result than one that runs seq.some(x=>pred(x)) or something to the effect of

let trueSeen = false;

for(const x of seq) if(pred(x)) trueSeen=true;

return trueSeen

will also return false.

Just at a glance, I'd expect false (every one of those strings yields NaN), yet the built in tools yield true.
Can anyone tell me what I'm missing?

Seems a bit harder than 7kyu

Lua translation!

Going for better UX by minimizing the number of clicks. Plus some of the examples at the top of the collection are bad groovy translations of mine.

Your link goes a bit too deep, maybe it would be just https://www.codewars.com/kata/526c7363236867513f0005ca/groovy or a link to the whole collection.
