✅ Javascript Reduce method Example.

▫️ Finding the longest word in a given string.

function longerWord(a, b) {
if (a.length > b.length) {
    return a;
  } else {
    return b;
}
}

const sentence = 'Hey there what are you doing this Wednesday night';

const longest = sentence.split(' ').reduce(longerWord);

console.log(longest);

// Wednesday
