lint - Sentence-count function not returning total count

Question

So i've been trying to create a sentence-count function which will cycle through the following 'story':

let story = 'Last weekend, I took literally the most beautiful bike ride of my life. The route is called "The 9W to Nyack" and it actually stretches all the way from Riverside Park in Manhattan to South Nyack, New Jersey. It's really an adventure from beginning to end! It is a 48 mile loop and it basically took me an entire day. I stopped at Riverbank State Park to take some extremely artsy photos. It was a short stop, though, because I had a really long way left to go. After a quick photo op at the very popular Little Red Lighthouse, I began my trek across the George Washington Bridge into New Jersey.  The GW is actually very long - 4,760 feet! I was already very tired by the time I got to the other side.  An hour later, I reached Greenbrook Nature Sanctuary, an extremely beautiful park along the coast of the Hudson.  Something that was very surprising to me was that near the end of the route you actually cross back into New York! At this point, you are very close to the end.';

And I realise the problem I'm having but I cannot find a way around this. Basically I want my code to return a the total sCount below but seeing as I've returned my sCount after my loop, it's only adding and returning the one count as a total:

const sentenceTotal = (word) => {
let sCount = 0;
if (word[word.length-1] === "." || word[word.length-1] === "!" || word[word.length-1] === "?") {
  sCount += 1;
};
return sCount;
};

// console.log(sentenceTotal(story)) returns '1'.

I've tried multiple ways around this, such as returning sentenceTotal(word) instead of sCount but console.log will just log the function name.

I can make it return the correct sCount total if I remove the function element of it, but that's not what I want.

Answer 1

I don't see any loop or iterator which would go through story to count the number of occurrences of ., ?, or !.

Having recently tackled "counting sentences" myself I know it is a non-trivial problem with many edge cases.

For a simple use-case though you can use split and a regular expression;

story.split(/[?!.]/).length

So you could wrap that in your function like so:

const sentenceTotal = (word) => {
  return word.split(/[?.!]/).length
};

let story = 'Last weekend, I took literally the most beautiful bike ride of my life. The route is called "The 9W to Nyack" and it actually stretches all the way from Riverside Park in Manhattan to South Nyack, New Jersey. It's really an adventure from beginning to end!

sentenceTotal(story)
=> 13
