// --- Directions
// Given a string, return a new string with the reversed
// order of characters
// --- Examples
//   reverse('apple') === 'leppa'
//   reverse('hello') === 'olleh'
//   reverse('Greetings!') === '!sgniteerG'

// Method 1
function reverse(str) {
  return str.split('').reverse().join('');
}

// Method 2
function reverse(str) {
  let reversed = '';

  for (let character of str) {
    reversed = character + reversed;
  }

  return reversed;
}

// Method 3
function reverse(str) {
  return str.split('').reduce((rev, char) => char + rev, '');
}

module.exports = reverse;
