<h2> 二、常用Composition API</h2>
<h3> 1. 初识setup</h3>
<h4> 1.1 setup的描述</h4>
<ol>
<li>理解：vue3.0中一个新的配置项，值为一个函数。</li>
<li>setup是所有<span style="color:#f20004">Composition API(组合API)</span> "表演的舞台"。</li>
<li>组件中所用到的：数据、方法等等，均要配置在stup中。</li>
<li>setupi函数的两种返回值：
<ol>
<li><strong>若返回一个对象，则对像中的属性、方法，在模板中均可以直接使用。（重点关注！）</strong></li>
<li><span style="color: #d3d3d3">若返回一个渲染函数：则可以自定义渲染内容。（了解）</span></li>
</ol>
</li>
<li>注意点：
<ol>
<li>尽量不要与vue2.x配置混用
<ul>
<li>Vue2.X配置(data、methos、computed.)中<span style="color:#f20004">可以访问</span>到setup中的属性.、方法。</li>
<li>但在setup中<span style="color:#f20004">不能访问</span>到vue2.x配置(data、methos、computed.)。</li>
<li>如果有重名，setup优先。</li>
</ul>
</li>
<li>setup不能是一个async函数，因为返回值不再是return的对象，而是promise,模板看不到return对象中的同性。</li>
</ol>
</li>

<p> 设计模式本身没有法则，但是设计模式所遵循的原则和规范可以被称为法则。</p>
<p> 以下是常见的设计模式法则：</p>
<ol style="padding-left: 5em;">
<li> 单一职责原则（Single Responsibility Principle，SRP）：一个类应该只有一个引起它变化的原因。</li>
<li> 开闭原则（Open-Closed Principle，OCP）：软件实体（类、模块、函数等）应该对扩展开放，对修改关闭。</li>
<li>里氏替换原则（Liskov Substitution Principle，LSP）：任何基类可以出现的地方，子类一定可以出现。</li>
<li>依赖倒置原则（Dependency Inversion Principle，DIP）：高层模块不应该依赖底层模块，二者都应该依赖其抽象；抽象不应该依赖细节，细节应该依赖抽象。</li>
<li>合成复用原则（Composite Reuse Principle， CRP）：尽量使用对象组合，而不是继承来达到复用的目的。</li>
<li>接口隔离原则（Interface Segregation Principle，ISP）：客户端不应该依赖它不需要的接口。</li>
<li>迪米特法则（Law of Demeter，LoD）：一个对象应该对其他对象保持最少的了解。</li>
