// The marketing team is spending way too much time typing in hashtags.
// Let's help them with our own Hashtag Generator!

// Here's the deal:

// It must start with a hashtag (#).
// All words must have their first letter capitalized.
// If the final result is longer than 140 chars it must return false.
// If the input or the result is an empty string it must return false.
// Examples:
// " Hello there thanks for trying my Kata"  =>  "#HelloThereThanksForTryingMyKata"
// "    Hello     World   "                  =>  "#HelloWorld"
// ""                                        =>  false
// ************************************************************************************

function generateHashtag(string) {
  if (string.trim() === '') return false;

  const stringWithCamelCase = string
    .split(' ')
    .map(word => word.charAt(0).toUpperCase() + word.slice(1))
    .join('');

  const stringWithHashtag = `#${stringWithCamelCase.trim()}`;

  return stringWithHashtag.length > 140 ? false : stringWithHashtag;
}

how does this code solve this test? assert.strictEqual(generateHashtag("code" + " ".repeat(140) + "wars"), "#CodeWars")
