Find the longest word in a String, is my solution good? [SPOILER!]

JavaScript
1

Hey!
I come up with solution that works:

function findLongestWord(str) {
  var str1 = str.split(" ").sort(function(a, b){
    return b.length - a.length;});
  return str1[0].length;
}

But i didn’t find anything too similar with my in this topic. Can you tell my if my is good or bad? And if bad, then why?

Hey, if it works, it works!

If you want to test the efficiency of your algorithm against the wiki answers, you can find a sample script here:

Hello, I have moved your post to the right category as it is not a wiki entry.

Messy Solution, but it worked!!

function findLongestWord(str) {
return str.split(" " ).sort(function (a,b){
return (b.length-a.length);}).join(" “).split(” “,1).join(” ").length;
}

findLongestWord(“May the force be with you”);

const findLongestWord = str =>
  Math.max(...str.split(' ').map(w => w.length))

function findLongestWord(str) {
str = str.split(’ ');
var a = [];
for (var i = 0; i < str.length; i++){
a[i] = str[i].length;
}
return a.sort(function(a,b){
return b-a;
}
)[0];
}
findLongestWord(“The quick brown fox jumped over the lazy dog”);

This is my solution:

const longestWord = (str) => Math.max(...str.split(' ').map((word) => word.length))

The dotdotdot part is ES6’s spread operator, to read more about it:

This is my solution:
function findLongestWord(str) {
var firstArray = str.split(" ").map(function(val){
return val.length;
});
var max = Math.max(…firstArray);

return max;
}

findLongestWord(“The quick brown fox jumped over the lazy dog”);

Here my solution:

function largestOfFour(arr) {
  return arr.map((a) => Math.max(...a));
}
