A very good W3school tutorial can be found here.

Javascript – Find the longest word in a String with a regex

function findLongestWordLength(str) {
  
  //Creating the regex and adding the solution in the array
  let word = [];
  let regex = /[A-Za-z]+S/g;
  let result = str.match(regex);
  word.push(result);
  
  //Iterating the array using forEach
  let currentWord = 0;
  word.forEach((element) => {
    element.forEach((element2) => {
      let longestWord = element2.length;
      if (currentWord < longestWord) {
        currentWord = longestWord;
      }
    });
  });
  
  //It returns the longest word (the length of that word)
  return currentWord;
}

console.log(
  findLongestWordLength("The quick brown fox jumped over the lazy dogs")
);

This is a good solution but can be this algorithm improved ?

Help me guys out to find a simplify solution

I need feedback about this code I made

Thanks

    Just compact and make it more readable and simplify it to this?

    function findLongestWordLength(str) {
    let maxLen = 0;
    str.match(/[A-Za-z]+S/g)?.forEach(s => {
        if (s.length > maxLen) {
          maxLen = s.length;
        }
    });
    return maxLen;
}

console.log(
  findLongestWordLength("The quick brown fox jumped over the lazy dogs")
);

console.log(
  findLongestWordLength("")
);

    Slightly shorter, return the longest word:

    const findLongestWord = str => str.split(/W{1,}/)
  .reduce((a, c) => c.length > a.length ? c : a, '');

console.log(findLongestWord(`I am a lonely pilgrim searching 
for stackoverflowishness in the wildermark.`));
// => stackoverflowishness

    Or if you just want the length of the longest word (your subject says the longest word but your code says the longest word length):

    const findLongestWordLength = str => str.split(/W{1,}/)
  .reduce((a, c) => c.length > a.length ? c : a, '').length;

console.log(findLongestWordLength(`I am a lonely pilgrim searching 
for stackoverflowishness in the wildermark.`)); // => 20
