### dom操作，一次性插入100个节点，和我分100次插入1个节点，哪个性能更高？
**答案**： 一次性插入100个节点性能更好。
**理解**：一次性插入100个，只对dom节点进行了一次操作，而分100次插入则操作了100次dom节点。插入节点时dom树每次会重新计算，生成新的dom树,渲染树也会跟着改变。浏览器会使渲染树中受影响的部分失效，重新绘制，因此也会进行100次重绘。影响性能。（也不知是影响cpu? Gpu? 还是浏览器--）。
### 问题
- ssr从服务器返回字符串，进行HTML渲染，是怎么返回的？以何种方式返回的？
- js解析主线程跟GUI渲染线程存在优先级吗？
