<p>解析HTML的时候需要注意JavaScript<strong>脚本的执行会阻塞HTML的解析</strong>，因此当解析HTML解析到一行外链脚本的时候，我们需要等待<strong>脚本的加载</strong>、再等待<strong>脚本的执行</strong>，才能继续后续HTML的解析。</p>
<p>如果我们不希望<strong>脚本的加载</strong>阻塞HTML的解析，我们可以给<code>script</code>标签加上<code>async</code>或者<code>defer</code>，此时该外链脚本的加载将不会阻塞后续HTML的解析（也就是解析后续HTML的同时并行加载该脚本，当该脚本被成功加载后则会停止后续HTML的解析并开始执行该脚本）</p>
<ul>
<li><code>async</code>：外链脚本加载完成后会立刻停止HTML的解析并开始执行该脚本</li>
<li><code>defer</code>：外链脚本会在整个HTML都被解析完成后（或者说<code>DOMContentLoaded</code>事件触发）才执行</li>
</ul>
