Why doesn't my code work?

Tell us what’s happening:
I’m trying to find the longest word in an array, this is what I’ve written so far (please do not laugh) but it works for some texts but not all. Why?

Your code so far


function findLongestWordLength(str) {
let strSplit = []
strSplit = str.split(' ');
let length = strSplit.map(word => {
  return word.length;
});
let strLength = length.sort();
let lastEle = strLength[strLength.length-1];
return lastEle;
}

findLongestWordLength("The quick brown fox jumped over the lazy dog");

It worked for me if I put a compare function in the sort method.

function compareNumbers(a, b) {
  return a - b;
}

so instead of just array.sort(), you put the function inside the sort parentheses.

Hello there,

Add this to your code to help you debug:

let strLength = length.sort();
// Add the console.log
console.log(strLength)

Also, read up on the .sort method: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/sort

Hope this helps
