#1

Tell us what’s happening:

Your code so far


function findLongestWordLength(str) {
  var longest ;
  var splitStr = str.split(" ");
  splitStr[0].length = longest;
  for (var i =0 ; i<str.length; i++){
   if (splitStr[i].length < longest){
     longest = splitStr[i].length;
   }

   }
  
  return longest;
}

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

#2

When does your for loop stop? What is the max value of str.length?
Looking at that might help you find your mistake!

#3

as @Capucine said read your code carefully and u will solve your mistake. if u can’t figure it out check this spoiler

Spoiler

your answer is changing i<.strlength to i<splitStr.length
