<li>过度设计</li>
<li>设计不足</li>
<li>测试驱动开发和持续重构 两个重要实践降低过度设计和设计不足的几率</li>
<li>重构与模式 密不可分的关系：在许多重构方法中，模式有助于改进设计。 许多时候我们通过重构实现模式，或者趋向模式进行重构。模式与重构之间存在天然联系。模式是你想到达的目的地，而重构则是从其他地方抵达这个目的地的条条道路。 </li>
<li>渐进式设计 => 重构实现模式或者重构趋向模式</li>
</ol>
<h2 id="重构"><a href="#重构" class="headerlink" title="重构"></a>重构</h2><h3 id="目的"><a href="#目的" class="headerlink" title="目的"></a>目的</h3><ol>
<li>使新代码的增加更容易 （降低耦合）</li>
<li>改善既有的代码的设计 </li>
<li>对代码的理解更透彻 </li>
<li>提高编程的趣味性 （减少dirty work，比如降低处理check in冲突的巨类的存在）</li>
</ol>
<h2 id="模式"><a href="#模式" class="headerlink" title="模式"></a>模式</h2><p>何谓模式？<br>每个模式是由三个部分组成的规则：</p>
<ol>
<li>某一个环境</li>
<li>一个问题</li>
<li>解决问题方案</li>
</ol>

<li>避免重复代码</li>
<li>提高阅读性</li>

<li>小函数串起来几乎对性能无影响， 对条件分支过长的 可以考虑用command 模式， strategy等模式来替换</li>
