--description--

Given a sentence, return the longest word in the sentence.

  • Ignore periods (.) when determining word length.
  • If multiple words are ties for the longest, return the first one that occurs.

--hints--

getLongestWord("coding is fun") should return "coding".

js
assert.equal(getLongestWord("coding is fun"), "coding");

getLongestWord("Coding challenges are fun and educational.") should return "educational".

js
assert.equal(getLongestWord("Coding challenges are fun and educational."), "educational");

getLongestWord("This sentence has multiple long words.") should return "sentence".

js
assert.equal(getLongestWord("This sentence has multiple long words."), "sentence");

--seed--

--seed-contents--

js
function getLongestWord(sentence) {

  return sentence;
}

--solutions--

js
function getLongestWord(sentence) {
  const words = sentence.split(' ');

  let longest = '';
  for (let word of words) {
    const cleanWord = word.replace(/\./g, '');
    if (cleanWord.length > longest.length) {
      longest = cleanWord;
    }
  }

  return longest;
}
