[removed] find longest word in a string

Question

function longestWord(string) {
    var str = string.split(\" \");
    var longest = 0;
    var word = null;
    for (var i = 0; i < str.length - 1; i++) {
                


        

Answer 1

I will refer you to this awesome article which defines three ways:

1 - Find the Longest Word With a FOR Loop

    function findLongestWord(str) {
  var strSplit = str.split(' ');
  var longestWord = 0;
  for(var i = 0; i < strSplit.length; i++){
    if(strSplit[i].length > longestWord){
    longestWord = strSplit[i].length;
     }
  }
  return longestWord;
}
findLongestWord("The quick brown fox jumped over the lazy dog");

2 - Find the Longest Word With the sort() Method

function findLongestWord(str) {
  var longestWord = str.split(' ').sort(function(a, b) { return b.length - a.length; });
  return longestWord[0].length;
}
findLongestWord("The quick brown fox jumped over the lazy dog");

3 - Find the Longest Word With the reduce() Method

function findLongestWord(str) {
  var longestWord = str.split(' ').reduce(function(longest, currentWord) {
    return currentWord.length > longest.length ? currentWord : longest;
  }, "");
  return longestWord.length;
}
findLongestWord("The quick brown fox jumped over the lazy dog");

Of course, it returns the length of the biggest word if you want to get the string, just get rid of the length in return part.
