Tell us what’s happening:

Hi, struggling to get this to return 0 when sentence = “”
I’ve tried using typeof (i.e if it isn’t a string returning 0 or if it is undefined returning 0)

Any help much appreciated!

(You can see various of my attempts in this code- I have been looking at it too long and am stepping away)

Your code so far

function getVowelCount(sentence) {
  const vowels = "aeiou";
  let count = 0;

  for (const char of sentence.toLowerCase()) {
    if (vowels.includes(char)) {
      count++;
    }
  }
  return count;
}

const vowelCount = getVowelCount("Apples are tasty fruits");
console.log(`Vowel Count: ${vowelCount}`);

function getConsonantCount(sentence) {
  const consonants = "bcdfghjklmnpqrstvwxyz";
  let count = 0;

  for (const char of sentence.toLowerCase()) {
    if (consonants.includes(char)) {
      count++;
    }
  }
  return count;
}

const consonantCount = getConsonantCount("Coding is fun");
console.log(`Consonant Count: ${consonantCount}`);

function getPunctuationCount(sentence) {
  const punctuations = ".,!?;:-()[]{}\"'–";
  let count = 0;

  for (const char of sentence) {
    if (punctuations.includes(char)) {
      count++;
    }
  }
  return count;
}

const punctuationCount = getPunctuationCount("WHAT?!?!?!?!?");
console.log(`Punctuation Count: ${punctuationCount}`);

function getWordCount (sentence){
  if (typeof(sentence) === "undefined"){
    return 0
  }
  let length = sentence.length
  const letters ="abcdefghijklmnopqrstuvwxyz"
  for (const char of sentence.toLowerCase()){
  if (!letters.includes(char)){
    return 0
  }
  else 
  {let count = sentence.trim().split(/\s+/).length;
  return count
  }
}}
console.log(getWordCount(""))

check console.log(typeof("")), does it give undefined?

thanks, this helped me work out I could just say if(sentence ===“”) - i really was pulling at straws by the time i posted this and didn’t think it was undefined but i needed a break haha
