LongestWord javascript

LongestWord javascript

Have you ever faced a situation where you need to find the longest word in a string? Well, JavaScript has got you covered. Here are a few ways you can achieve this:

Method 1:

You can use the split() method to split the string into an array of words and then use a loop to iterate through the array and find the longest word. Here's the code:

function longestWord(str) {
  var words = str.split(' ');
  var maxLength = 0;
  var longestWord = '';

  for (var i = 0; i < words.length; i++) {
    if (words[i].length > maxLength) {
      maxLength = words[i].length;
      longestWord = words[i];
    }
  }

  return longestWord;
}

console.log(longestWord('The quick brown fox jumped over the lazy dog')); // Output: 'jumped'

Method 2:

You can also achieve this using the reduce() method. Here's the code:

function longestWord(str) {
  var words = str.split(' ');

  var longestWord = words.reduce(function(longest, currentWord) {
    return currentWord.length > longest.length ? currentWord : longest;
  }, '');

  return longestWord;
}

console.log(longestWord('The quick brown fox jumped over the lazy dog')); // Output: 'jumped'

Method 3:

If you want to be fancy, you can use map(), sort(), and pop() to achieve the same result. Here's the code:

function longestWord(str) {
  var words = str.split(' ');

  var sortedWords = words.map(function(word) {
    return word.replace(/[^\w]/g, '');
  }).sort(function(a, b) {
    return b.length - a.length;
  });

  return sortedWords[0];
}

console.log(longestWord('The quick brown fox jumped over the lazy dog')); // Output: 'jumped'

These are just a few ways you can find the longest word in a string using JavaScript. Choose the one that works best for your use case.
