Basic Algorithm Scripting: Find the Longest Word in a String

JavaScript
1

Hello all,
I have posted my code below and fee the logic is correct (all be it not the most elegant). When I run the code in another environment (brackets) I can get the largest number to console.log but not return. The free code camp site will not even run the code. Any suggestions would be appreciated;

function findLongestWordLength(str) {
  var counter =0;
  var number =[];
  var b =0;
for(var i=0; i< str.length; i++)
  if(str[i] !== ' '){
    counter +=1;
  }else{
    number[b] = counter;
    b++;
    counter = 0; 
  }

 var largest = 0   
    
for(var c =0; c <=largest ; c++){
    if(number[c] > largest){
        largest = number[c];
    }
    
}
  return largest;
  
}

can you post the challenge link this is for?

Wow thank you !! will keep at it but this helps a ton thanks again!

Use var res = str.split(" "); to get split string at place of every " " and after just count length of every member array.

It’s not an elegant code, but it definitely works

function findLongestWordLength(str) { 
  let longWord = str.split(' ')[0].length;
  for (let i =1; i < str.split(' ').length; i++) {
    //Traversing the length of the array
    let curWord = str.split(' ')[i].length;
    // compare one by one...
    if (longWord < curWord ) {
        longWord = curWord;
    }
  }
  return longWord;
}
let con = findLongestWordLength("May the force be with you");
console.log(con);
8 
function findLongestWordLength(s) {
  
    return s.split(' ').reduce((acc, cur) => {
      return Math.max(acc, cur.length);
    },0);

}
let con = findLongestWordLength("The quick brown fox jumped over the lazy dog");
console.log(con);
