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

I would do something like this:

function longestWord(str){
  return str.match(/\w+/g).reduce((p,c) => p.length > c.length ? p.length:c.length);
}

Answer 2

function findLongestWord(str) {
  //This is what I  used to find how many characters were in the largest word
  return str
          .replace(/[^\w ]/g,'')                            
          .split(' ')                                       
          .sort(function(a, b) {return a.length-b.length;}) 
          .pop().length;                                           

}
findLongestWord('The quick brown fox jumped over the lazy dog');

Answer 3

Your return statement is in the wrong place, as mccainz said, however you should also be saving the word if you want to return the actual word.

function findLongestWord(str) {
  var words = str.split(' ');
  var longestLength = 0;
  var longestWord;
  for (var i=0;i<words.length;i++) {
    if (words[i].length > longestLength) {
       longestLength = words[i].length;
       longestWord = words[i];
    }
  }
  return longestWord;
}

Answer 4

Here's a functional approach:

function findLongestWord(str) {
  return str
          .replace(/[^\w ]/g,'')                            //remove punctuation
          .split(' ')                                       //create array
          .sort(function(a, b) {return a.length-b.length;}) //sort in order of word length
          .pop();                                           //pop the last element
}

console.log(findLongestWord('For the next 60s, we will be conducting a test.')); //conducting
