Yeah, that can save a lot of regex

Nobody is going to want to read that description; it's full of typos, invalid punctuation, and is an unsegmented block of text. Look into learning some markdown and use a spell-checker for your descriptions.

i have modified it
please share your thoughts

thanks for your comment
ill make sure to correct it

function fleschKincaid(text){
  let vowels = (text.match(/[aeiou]/g)||[])
  let words = text.split(" ")
  let sentences = text.split(/[!.?:;]/).filter(Boolean)
  return (0.39 * (words / sentences)) + (11.8 * (vowels / words) ) - 15.59;
}

It's not since we can't pass that kata by just changing the multipliers:

Flesch–Kincaid Grade Level is for mapping to a School grade, While Flesch reading ease is to get a more general idea. Both formulas are different

Thankyou for your feedback - it is encouraging and constructive. I appreciate that the katas do test the same skills as some of the others and I will un-publish them

Thanks for pointing it out @daniloxxv, I have fixed and republished the kata.

Ture that. I've mistakenly put it there. The kata has been edited. Thanks for the feedback!

Couldn't yet make the other solution work for that though. Seems there actually is a difference between x !== x or ! (x === x), and assert.notStrictEqual(x,x), or something.

Oh well... x(

nothing. Or just burn a candle... x)

Never mind, it got retired as I was replying :D What can I do with it now?
