当然我们可以用lazy+suspense进行代码分割,这也是react官方推荐的方法,suspense组件fallback属性,可以设置对应的备用UI

那react中没有两个生命周期组件,我们需要如何捕获项目中的异常呢?sentry的实现方法?
- try catch
- window.onError:setTimeout的报错是try catch无法捕获的,但可以用window.onError捕获
- Window: unhandledrejection event:promise的报错是封存在内部的,外部无法感知,我们可以监听unhandledrejection事件,当Promise 被 reject 且没有 reject 处理器的时候,会触发 unhandledrejection 事件
