"Only use ~~ as a substitution for Math.trunc() when you are confident that the range of input falls within the range of 32-bit integers."

This is essentially an easier version of [https://www.codewars.com/kata/5e787d8b4a26820028d5ac6c/haskell] (which has received almost no attention in three years).

The kata above is more challenging because there isn't time to simply iterate through up to a billion numbers adding up the lengths as you go.

I stranded at 49 :)
edit: 47 \o/

I love those as well. It's so interesting. I always look up what they're about if no one explained them in the replies. It's fun to know that those fancy options exist.

This is the kind of solution I adore in the easier kyu range. Not too wild, but wild enough to make me go, "ooooh."

• Selecting tests from a fixed pool of tests does not make it "random tests"

• Description should be language-agnostic

• Node 12 should be enabled

• Random tests should have more edge cases added

Didn't know about that operator. Not anymore

I'm stuck at 52 :( Feeling ready to give us and not find the solution... I'm not sure if it's a trick with regex or something in the counting that I could be doing different!...

wow bravo !
