Tell us what’s happening:
Describe your issue in detail here.
I solved the challenge in another method. But i would like to know why this code doesn’t work. The elements of words list is not being passed to word variable in for loop but i don’t know why?

Your code so far

function findLongestWordLength(str) {
  
  let words = str.match(/\w+/ig);
  //console.log(words)
  let longestWord = "";
  for (let word in words) {
    console.log(word)
    if (word.length > longestWord.length) {
      longestWord = word;
    }
  }
  console.log(longestWord.length)
  return longestWord.length;
  
}

Hello,

Your for...in loop is the culprit here. For...in is used to iterate of the properties of an object. For...of is used for arrays.

This article talks a bit about what is going on behind the scenes when you called for...in on an array object.
