find longest word in a string

Question

Currently trying to figure out how to find the longest word in as string and my research has gotten me somewhere. I found a code on SO that shows the amount of alphabets in

Answer 1

I recommend this approach:

function LongestWord(text) {
    return text
              .split(/\s+/)
              .reduce(function (record, word) {
                  if (word.length > record.length)
                      record = word;
                  return record;
              }, '');
}
console.log(LongestWord('It is obvious which is the longest word.'));

If you want to return the length of the longest word, just add .length to the end of the return.

Answer 2

There you go:

function longest(str) {
  var words = str.split(' ');
  var longest = ''; // changed

  for (var i = 0; i < words.length; i++) {
    if (words[i].length > longest.length) { // changed
      longest = words[i]; // changed
    }
  }
  return longest;
}
console.log(longest("This is Andela"));

Answer 3

I think the easiest solution is to split, sort the array by length and then pick the first element of the array.

function longest(str) { 

 var arr = str.split(" ");

 var sorted = arr.sort(function (a,b) {return b.length > a.length;});

return sorted[0];

}

If you want the length, just add .length to return sorted[0].
