Find the longest word in a string using javascript

Question

I\'m trying to find the longest word in a string, but it continually returns the length of the first word. Any ideas?

Here\'s my code:

function findL         


        

Answer 1

Here is how I did it (I enclose a commented long version and a uncommented short version):

 /***************
 * LONG VERSION *
 ***************/
function findLongestWord(str) {
  // Create an array out of the string
  var arr = str.split(' ');

  // Sort the array from shortest to largest string
  arr = arr.sort(function(a, b) {
    return a.length-b.length;
  });
  // The longest string is now at the end of the array

  // Get the length of the longest string in the Array
  var longestString = arr.pop().length;

  // return the lenght of the longest string
  return longestString;
}

/*****************
 * SHORT VERSION *
 ****************/
function findLongestWord(str) {
  return str
    .split(' ')
    .sort(function(a, b) { return a.length-b.length; }) 
    .pop().length;
}
