Find the Longest Word in a String - answer seems correct

JavaScript

Tell us what’s happening:

Hi all,

I tested my solution in Chrome console and it returned the correct result every time. However it is not passing any of the tests on the FreeCodeCamp side. It is returning the following:

assignment to undeclared variable i

Any direction is appreciated. I have tested it with the strings for the tests it must pass and in console it returns the correct answers.

Your code so far


function findLongestWordLength(str) {
  var strSplit = str.split(' ');
  var longestWord = strSplit[0].length;
  for (i = 0; i < strSplit.length; i++) {
    if (longestWord < strSplit[i].length) {
      longestWord = strSplit[i].length;
    } 
  } return longestWord;
}

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

the error message is correct you never declared i
try this:
for (let i = 0; i < strSplit.length; i++;)

Oops! it’s the darn little things right haha. I haven’t been coding enough lately to remember proper syntax apparently. Chrome was nice enough to overlook that. Thanks for the direction, that worked!

I just started at the beginning and am working my way through the tutorials and challenges. It’s important to take some time and do an internet search when you get stuck, to see if you can figure it out without asking first. It can seem difficult at times but keep at it and you will learn over time.
