Find the longest word in a string?

Question

I am trying to write a basic javascript function to find the longest word in a string and log it\'s length.

So far I have:

function findLongestWord(         


        

Answer 1

Here is another shorter version:

function findTheLongestWord(str) {
  var temp = '';
  (str || "").split(/\s+/).forEach(function(word) {
    temp = word.length > temp.length && word || temp;
  });
  return "longest word is: " + temp + " and it's length is: " + temp.length;
}

alert (findTheLongestWord("The quick brown fox jumped over the lazy dog, once again!"));
