解法

• 暴力解法

  function likes(names) {
  if ( names.length === 0){
    return 'no one likes this'
  }else if ( names.length === 1){
    return `${names[0]} likes this`
  }else if ( names.length === 2){
    return `${names[0]} and ${names[1]} like this`
  }else if ( names.length === 3){
    return `${names[0]}, ${names[1]} and ${names[2]} like this`
  }else if ( names.length > 3){
    return `${names[0]}, ${names[1]} and ${names.length - 2} others like this`
  }
  }
  

• 轉換成switch

  function likes(names) {
  switch (names.length) {
    case 0:
      return 'no one likes this'
    case 1:
      return `${names[0]} likes this`
    case 2:
      return `${names[0]} and ${names[1]} like this`
    case 3:
      return `${names[0]}, ${names[1]} and ${names[2]} like this`
    default:
      return `${names[0]}, ${names[1]} and ${names.length - 2} others like this`
  }
  }
  

  ### 筆記
  因為有多種不同的結果
  先使用了暴力解法後
  發現也可以使用switch
  這樣在閱讀上更易讀一些
